What plants are safe to have in the house with cats?

Now that we’ve established some plants are toxic, let’s go through the permissible ones for a house with cats.

Orchids

Another beautiful flower is the Orchid which comes in many variants like the Cocktail orchid and Brazilian orchid. You can also find Dancing Doll Orchids and Golden lace orchids, to name a few.

While they can be gorgeous, it’s essential to know whether they are harmful. We’re happy to report that orchids are safe for cats and will only cause a mild tummy ache in the worst-case scenario if ingested.

But the ASPCA reports that all types of orchids are non-toxic. However, there are over 25000 species of orchids. It’s best to consult a professional if you’re unsure.

Succulents

There’s good news for succulent owners and lovers. Most pets will avoid them by instinct. Most varieties of succulents are completely non-toxic to cats. Since they don’t smell delicious enough, they will avoid ingesting or touching them.

Rose

Beautiful rose bushes are a popular choice in the garden. The good news is that all varieties of the rose family are safe for cats! However, beware of other plants with ‘rose’ in the name but belong to a different genus.

For instance, the Christmas rose is poisonous to cats but belongs to the buttercup family. The Desert rose is part of the dogbane family. It has a milky sap that can prove dangerous.

For a detailed list of ones with ‘rose’ in the name, check the table for toxic and non-toxic options.

Here are a few examples of some plants which have ‘rose’ in the name and might or might not be toxic for cats.

Spider Plant

The spider plant is also known as spidery ivy and ribbon plants. It is non-toxic to cats, as stated by the ASPCA. But it is attractive since it can produce hallucinogenic effects in the furry species.

When ingested, it can only cause a mild stomach ache or vomiting. It is the natural reaction to the ingestion of something like grass.

Lilacs

Another highly attractive and sweet-smelling flower is the lilac. Lilacs are usually deemed safe, except for a couple of varieties. Species like the Persian lilac and French lilac are highly toxic.

They cause severe abnormal symptoms like gastrointestinal problems and seizures. The symptoms can take 3-4 days to develop, so keep an eye on your kitty if he/she has been around the flowers.

So, her name is Lela. Lilacs did not inspire it, but we’re pretty sure she has a special connection with them.

Christmas cactus

Christmas cactus is likely to appear during the holiday season when it’s also their blooming season, hence the name. You can let your pets roam around the house in peace with this plant in the house since they are perfectly safe for all furry friends!

African Violets

African violets are stunning plants that flower in pretty pinks and reds. You’ll also find them in blues and whites in all seasons. The good news is that you can let your kitties roam around freely without any fear of African violets!

Sunflowers

Here’s an exciting piece of news to brighten your day. Sunflowers are safe for everybody, cats included! The ASPCA says happy flowers are safe for both humans and pets. Your cats can go rummaging in those garden beds!

Basil

Here’s good news for plant and pesto lovers. Your favorite Italian herb is safe for your cats and kittens too! Basil is a favorite of chefs and cats due to its intense flavor and smell!

Basil should be in everyone’s diet. Some of its benefits include:

• Boosts the immune system
• Reduces fever
• Protects the liver
• Reduces symptoms of depression
• Improves digestion

Unlike other herbs, this one is safe in any form for your cats. It doesn’t matter if it’s powder or fresh basil leaves.

Fern Plants

Fern plants are house options that aren’t toxic to cats. Just ask Garfield, the fern lover! However, many varieties with fern in the name and properties resembling the plant can be very toxic.

Asparagus fern and Emerald Fern are a no-go. Lace Fern and Fern Palm are also toxic varieties with ‘fern’ in the name. Make sure always to look up the name and double-check its toxicity before bringing in a house with cats.

Marigold

Clusters of bright orange and yellow marigolds are a sight for sore eyes, and guess what? They’re completely non-toxic. Not only can your kitties run freely in marigold beds. Your home can stay insect-free since marigolds are naturally insect repellent, especially for mosquitoes!

These dragon fruits are also 100% safe to have!

Petunias

If you’re looking to add a spot of color to the house, Petunias come in any color imaginable. The best part is they are completely safe to be around all kinds of pets. It includes cats, dogs, horses, and rabbits. If you’ve got a tortoise, petunias can safely become a part of their diet.

Pansies

Pansies are naturally multi-colored flowers to make one stop and stare. Your pets can be in awe of these since they are completely non-toxic. The ASPCA says no ill effects are reported even if ingested.

Snapdragons

Snapdragons are long colorful flowers that owe their name to the dragon-like appearance that forms when squeezed laterally. Snapdragons are completely non-toxic for cats and other pets.

If you’re worried they’ll become food for deer in your area, don’t worry. Deer will usually avoid eating snapdragons until they have to – so it’s a win-win!

Jasmine

The jasmine is one of the ones you need to research slightly more before planting or buying in a house with cats. The common jasmine and others like cinnamon jasmine and star jasmine are harmless around pets.

Other varieties may end up being very toxic. The toxic ones with ‘jasmine’ in their name include Cape Jasmine and Paraguayan Jasmine.

Rosemary

Rosemary is a versatile herb used in cooking, and some believe it has certain healing powers. Not only does it help with digestion skin and hair solutions, but it can also stimulate memory and boost alertness.

And the best part is that it’s perfectly non-toxic. They will most likely stay away from its strange smell and spikey texture.

Cilantro/ Coriander

Cilantro is another flavorful herb used in continental and Asian cuisine like basil. And just like basil, these tasty leaves can be chewed by your kittens too. Cilantro or coriander is completely non-toxic.

Hibiscus

The ASPCA classifies the hibiscus plant known as the Rose of Sharon and Rose of China as non-toxic to cats and dogs.

However, some sources claim that some pets’ mild irritation can be expected if they consume too much.

Palm

Palm plants make for a grand entrance at any hotel reception or resort. The good news is those common varieties like the Areca and Lady palm are non-toxic to cats and dogs.

However, beware of those with palm in the name but aren’t part of the palm family. For instance, the Sago palm is a cycad and is highly toxic to pets.

Take a look at other similar plants with Palm in the name to end the confusion, once and for all.

Pine Needles

All types of pine are completely non-toxic, so bring in the festive season with cheer. Due to their sensitive nature, most cats will steer clear of pine needles.

If you think your cat is too curious, avoid keeping them around pine needles. If ingested, pine needles can lead to complications in the intestines and cause blockage.

Majesty Palm

No beach is complete without a majesty palm lining the shore. Even though we doubt that cats will be able to climb the majesty palm tree, you’d be glad to know that it is completely non-toxic. So you can take your cat along on vacation!

Zinnias

Zinnias are stunning flowers, part of the sunflower tribe and the daisy species. They can qualify as twins of dahlias. Unlike dahlias, they are fully pet-friendly! Zinnias are non-toxic, so you curious kitten can safely sniff and munch them without your supervision.

Gerber Daisy

Here is a Daisy that isn’t poisonous to cats – the Gerber Daisy. Gerber daisies are bright and eye-catching and will bring a smile to anyone’s face, including your cat.

Venus Flytrap

You’d think the Venus flytrap is as harmful as it is to insects and flies. But that is not the case. Venus flytraps are completely non-toxic. Even if nibbled by them, your kittens won’t be too hurt.

Blueberries

Blueberries are a super-food for humans, thanks to their power-packed anti-oxidants. Those very anti-oxidants are great for cats, so some cat food contains blueberry powder. As a result, blueberries are non-toxic.

Bromeliads

Bromeliads are great for pet-owners and gardening novices, thanks to their hassle-free care. Not only do bromeliads thrive with little care in your home. They can also go soil-free and are completely non-toxic!

Echeveria

An Echeveria succulent is a plant lover’s dream because of its striking beauty and easy care. And it gets better. They’re completely non-toxic! That’s not something you can say for all succulents!

Impatiens

Beautiful touch-me-not flowers, otherwise known as Impatiens house plants, are safe. So the touch-me-not rule doesn’t apply to your pets for this one!

Alstroemeria

Alstroemeria’s one-of-a-kind beauty makes it a must for every bouquet and table arrangement.

The long shelf life assures they’re beautifying your home for a long time. Also known as the Peruvian Lily and Lily of the Incas, it is safe around your pets too!

Which plants are most toxic to cats?

Before getting plants in a house with pets or bringing pets into a house, know which ones are most toxic for cats. Keep reading our extensive list of what to avoid.

Poinsettias

The festive season will around pretty poinsettias to liven up the house and add a pop of color. But did you know that they can irritate kittens and cats? While poinsettias won’t prove fateful, they can irritate due to the chemical diterpenoid phorbol esters.

The milky sap of poinsettias can cause symptoms like digestive issues and drool. Watch out for vomiting and skin irritation like swelling. Redness and general irritation can also occur.

However, these symptoms will rarely require medical attention and will heal quickly with time.

Peace Lilies

Peace lilies are a plant known for their incredible ability to grow under almost any condition. They aren’t ideal for a pet lovers’ home since the leaves contain a dangerous element named calcium oxalate.

It can dissolve and damage deep into the tissues of cats even before ingested and deeply damage the tongue.

Tulips

Tulip fields look romantic, but they aren’t the best place to take your pets along. Think again if you’re thinking about gifting them or putting them in a house with kitties. Tulips are from the lily family and contain glycosides that can be fatal.

With toxicity in leaves and bulbs, it’s best to steer clear of the whole thing if you’ve got cats. Once tulips have been ingested, you will notice the following symptoms in your cat:

• Lethargy
• Abdominal pain
• Diarrhea
• Vomiting

Geranium

Geranium flowers are part of the Pelargonium genus that has many varieties. Unfortunately, these beautiful additions can prove very harmful. Even the water from the Geranium’s vase can cause your pet to have stomach problems, lethargy, vomiting, and loss of appetite.

Chrysanthemums

Mums or Chrysanthemums are common seasonal options to be seen in the winter. Little did you know that the leaves and flower heads can be very toxic!

Chrysanthemums are of many types, including the daisy variety. All these types must be confirmed for toxicity to cats before buying or including at home.

Let’s look at all the daisies and what to do with them:

Snake Plants

Snake plants are one of the toughest varieties to exist, and that’s why they’re present in almost all homes.

But the bad news is that the compound called saponins can cause nausea and diarrhea when swallowed. So, it’s in your pet’s interest to never let them sink their teeth into this one.

Daffodils

Daffodils are gorgeous to write poems on, but they’re a big ‘no’ around cats. Like hyacinths, the bulb of daffodils contains elements that can deeply irritate the tissues of the tongue.

It can penetrate deeper to cause further problems. The symptoms to watch out for are drooling and seizures. Look out for increased heart rate and gastrointestinal problems. Difficulty breathing is also something your furry friend may experience.

Peonies

Peonies make for a grand entrance at any walkway or bushes on your front lawn during springtime.

But did you know peonies can be poisonous for your pets? The toxin Paeonol will cause vomiting in your pets if ingested. Look out for signs of lethargy and fatigue if you’re worried about exposure.

Aloe Vera

Aloe vera may be full of healing properties for skin and hair but is not a good option to keep around cats. Aloe is only mild to moderately discomforting if ingested. You can avoid this by spraying it with vinegar in high places away from your pet’s reach.

Begonias

Begonias are both versatile and have unique colored leaves and blooming flowers. These same features of the begonia can cause severe burning sensations and huge discomfort if ingested by a kitty.

They can cause vomiting and diarrhea. Kidney failure is even a risk. The important thing to note is that most of the toxic portion is beneath the soil in potted plants and beds.

Calla Lilies

As mentioned earlier, all lilies are good to steer clear of when you’re a cat owner. Even though they aren’t fatal with Calla lilies, you should bear the same precaution.

They won’t bear much effect on the organs. The calcium oxalate crystals can damage your kitty’s tongue, mouth, and esophagus.

Other types of harmful lilies include

• Belladonna Lily
• Saint Joseph Lilly
• Lily of the Valley
• Arum Lily
• Pig Lily
• Barbados / Fire / Fire of the palace Lily

Amaryllis

Amaryllis is the only genus in the family of Amaryllidaceae and bears beautiful bulbous flowers. They include the Bella Donna lily and Naked Lady: Look out for Saint Joseph Lily, too.

But we regret to inform you that it is off-limits and very toxic for both cats and dogs. The lycorine puts cats and dogs at risk of stomach problems and lethargy. Tremors are also a common side effect.

Lavender

The soothing lavender is healing in both its smell and application for humans. Still, those kitty paws should be kept far from the reach of any form of lavender.

The ASPCA makes it clear the linalool and linalyl acetate present in lavender can lead to damage to the nervous system and liver if inhaled or ingested.

Daisies

There are many varieties of daisies and many plants with ‘daisy’ in the name. But if you’re looking to include the common daisy or the chamomile variety, be sure to know they are very toxic.

Varieties like the African daisy and Barberton daisy are non-toxic for cats. So is the Gerber daisy. They come in very vibrant colors, but make sure they’re okay to keep around the house!

Devil’s Ivy

As the name suggests, the Devils Ivy or Pothos plant might be a great addition to a high wall or a balcony. It is very toxic for your cat. It is safe to keep them away from farm animals like sheep and chickens.

Carnations

Carnations make great gift bouquets for loved ones in their pinks, wild and sweet William varieties.

But they can quickly become a cause for distress if the house cats start chewing on them. Carnations are toxic and can cause irritation to the stomach and lead to diarrhea or vomiting in pets.

Dahlias

Dahlias are the favorite of spring lovers everywhere. They’re very toxic. The symptoms of ingestion include skin irritation and itching. Look out for diarrhea and loss of excessive fur, too. Take your pet to the vet immediately if you spot these signs.

Bamboo

Like daisies, it’s important to know the details of the bamboo. Some versions of the bamboo are toxic if ingested, like Heavenly or sacred bamboo. Other options like Golden bamboo and Bamboo vine are considered non-toxic by the ASPCA. So is the Bamboo palm.

Toxic plants with the name ‘bamboo’ include

• Heavenly bamboo
• Sacred Bamboo

Non toxic include :

• Golden bamboo
• Fishpole Bamboo
• Bamboo Palm
• Bamboo vine
• Bamboo
• Red- berried bamboo

Grapes

Now here’s a shocker no one would expect – grapes are more toxic to cats than chocolate! Even in a grape plant, the stems and leaves are hard to digest. They lead to further health problems.

Coleus

The coleus plant or Spanish thyme has vivid patterns that make it a favorite among people wanting to spruce up their homes. Coleus can unfortunately severely burn any kitty, even if they brush past coleus.

Their oils act as irritants for your furry friend’s skin. Ingestion can lead to even worse symptoms like diarrhea and blood in the stool. Depression and lethargy are something else you’ll want your furry friend to go without.

Philodendrons

The Philodendron family includes the likes of the fiddle leaf and Swiss-cheese plant. They make for a great showstopper in any living room or porch area. But sadly, these qualify as mild to moderately toxic. Keep their paws away from them!

Baby’s Breath

The popular baby’s breath is breathtaking when it becomes part of any arrangement or garden bed. However, you must know this one classifies moderately toxic for our feline furry friends. It is slightly poisonous and can cause anorexia and vomiting.

Ivy

The Branching or sweetheart ivies are well-known creeping and climbing plants known to appear in Shakespearean balconies.

But it’s no longer romantic when you find out that it’s toxic for your kitten. Part of the Hedera family contains triterpenoid saponin. It can lead to many stomach problems and hypersalivation. Lethargy is another symptom of Ivy exposure.

Day Lilies

The name might fool you, but Daylilies aren’t part of the lily family. They’re part of the Hemerocallis family. These stunning home additions blossom in the morning and die by nightfall, hence the name.

But as mentioned before, it’s best to avoid any type of lily entirely when you are a cat owner. Even daylily variety can prove very toxic.

Gardenias

Gardenias are creamy-white flowers in unique shapes and sizes with many lower classifications like Cape jasmine and gardenia thunbergia.

But these unique options contain geniposides and gardenosides that are toxic for cats and other pets. Digestion issues and breaking out in hives are common signs if it is ingested.

Jade

While the jade plant is considered a sign of good luck in many countries, its poisoning is a serious condition. If left untreated, the toxic jade can even lead to death.

Anthurium

Anthurium is a flowering plant that is shell-shaped and grows in vibrant colors. It makes it the number one choice for a lovely bouquet. Due to their shape, they’re also called Painter’s palette and Flamingo Plant.

Unfortunately, calcium oxalate crystals in it can be very detrimental to any cat’s health. So they are classified as toxic by the ASPCA.

Sun star

The sun star is a lesser-known but equally attractive orange flowering option. It’s also known as the Orange Star or Star of Bethlehem.

These indoor varieties are great for brightening up corners of your home but, sadly, are very toxic for cats and dogs. Even water from their vase can lead to toxicosis in pets.

Dracaena

You may have noticed that house plants generally consist of species of the Dracaena genus. They consist of no-fuss shrubs and succulents that survive under almost any condition.

But no matter how attractive, Dracaena should be kept away from a house with pets. Eating Dracaena can lead to toxic reactions like diarrhea and vomiting.

Eucalyptus

You might have seen cute pictures of koala bears munching on eucalyptus leaves and thought they must be safe around your furry pets too.

You’ll be surprised to know that eucalyptus is highly toxic to cats. Koalas are one of the only mammals that can safely consume and survive on a diet of eucalyptus leaves.

Iris flowers

Iris flowers take their name from the Greek word meaning rainbow. It is symbolic of the wide variety of colors found in nature. The flashy colors are enough to dazzle your entire front yard or porch.

Unfortunately, most varieties of Irises are moderately toxic for cats. The Butterfly iris and Water flag are both toxic varieties. So is the snake lily, to name a few.

Tomato Plants

Tomatoes are a tricky one. While your kitten can safely munch on ripe tomatoes, the stem and leaves contain the toxins unsafe for consumption. The unripe fruit is also a problem. The solanine compounds in the stem and leaves are toxic for small animals.

Oriental Lilies

As mentioned before, all lilies are very poisonous. It includes the Lily ‘Stargazer’ or Oriental variety. It’s safe to say you should avoid any kind of lilies in a house with cats.

Crotons

Crotons have bright red, yellow, and green leaves that can stir curiosity in any kitten. But you should know to keep your cats away from Croton since any kind of chewing and biting can lead to burning sensations and rashes.

The Wandering Jew

The wandering jew or the Inchplant is part of the spiderwort species and has unique green and maroon leaves.

You can place them in a pot to stun guests, but sadly it is toxic to cats and hence a big no for homes with these pets. The sap can harm the digestive tract of your pets.

Kalanchoe

Kalanchoe is a unique succulent that blooms tiny flowers similar to a baby’s breath. Also known as Widow’s thrill and Mother of Millions, it can cause gastric problems and even abnormal heartbeat in cats. Keep these toxic ones well out of reach of kittens.

Mint

But on the other hand, American rubber plants and blunt leaf peperomia are listed as non-toxic by the ASPCA. So are the pepper face ones.

Yucca cane

Yuccas are rare and only found in certain parts of the Americas and the Caribbean. This attractive cane consists of white waxy flowers and is mostly stem-less.
