Our adorable feline friends have taken over our homes and lives, but certain aspects of a house cat’s life can still be quite dangerous. When it comes to the houseplants you keep, you absolutely must do your homework. Even if a plant does not have toxic or poisonous properties, it does not mean it can’t harm your cat. This also applies to outdoor cats that might cross paths with poisonous plants.

 

Pothos and Other Vining Houseplants: Safe for Cats?

Many people bring their houseplants outdoors in warmer weather to get some fresh air and direct sunlight, then bring them back indoors when the weather becomes cold. The question and possible threat remain the same whether outside or inside: some plants are toxic to our cats. Having an inside cat is vastly safer, but not without all danger. We may not consider the dangers our houseplants hold for our indoor feline friends. Obviously, cats who venture outdoors come in contact with far more on the danger scale, but house cats aren’t without their own dangers. It is crucial to know which plants can live inside and not poison your cat if they take a nibble.

 

Different Types of Pothos

 

Though they are neat plants and a favorite of many, they are toxic to cats. They are not poisonous, so they do not affect the kidneys or liver, but they can damage your cat’s soft tissue in their mouth, throat, stomach, and gums. This is due to the leaves and stems of the pothos containing a chemical called calcium oxalate, which is in crystallized form. Cats cannot break down the chemical, resulting in a very sore mouth or worse. It is not fatal but can cause the cat to become anorexic or dehydrated because they will want to avoid doing anything that brings further pain to their mouths. Because of this critical side effect, cats who stop drinking must receive IV fluids at the vet or face a grimmer outcome. Though this is alarming, don’t let owning a cat become a negative aspect of your life. Studies show that people living with a cat are happier and healthier overall.

 

Other Vining Houseplants

This is an easy-to-care-for starter plant that doesn’t require a lot of light and is overall low maintenance. The hearty peperomia family is not toxic to cats, dogs, or children. However, it is still always best to keep the plant off the floor, where having a quick bite is easier.

This plant is also called the donkey’s tail and is a great starter plant because it is easy to care for. It is a succulent and doesn’t require very much water. All they need is some extra bright light and well-draining soil to flourish. They make an exciting target for your professionally curious cat, but don’t worry; these plants are nontoxic to cats and dogs for the most part. If you suspect a large quantity has been ingested, they can be mildly toxic and warrant a trip to the vet.

 

Climbing Begonia

Climbing begonias can be a lovely addition to your plant collection if you do not have any pets. They are beautiful and grow up to twelve feet long and wide. This plant can make for some really neat decorating inside your home. Though not toxic to cats or dogs, they can cause gastrointestinal upset if too much is eaten. The calcium oxalate crystals are found throughout the plant, though the highest concentration is in the plant’s roots. Eating even a tiny amount can cause soft tissue damage inside your cat’s mouth, throat, and stomach. This will cause drooling, possible issues eating and drinking, and problems swallowing.

 

Dischidia Oiantha

Dischidia is not toxic to pets but can cause stomach upset due to all the fiber-packed into it. In large quantities, it can cause vomiting and diarrhea. If you think your cat has ingested some of the plants, take them to the vet. The internet is filled with contradicting info on dischidia and pets. One thing is for sure: this isn’t a tasty treat for cats, and it should be kept out of their reach. If Mr.FuzzyPants does indulge in a bit of dischidia, try to have them drink water to flush it out.

 

String of Turtles

String of Turtles, like all peperomia plants, are nontoxic to cats and dogs. They are fun, easy to grow, and cared for, making them an excellent plant for busy people or people just starting out in the hobby. Though the “turtles” won’t cause serious issues with your cat, caution should be used. If your cat does eat a bit, it’s possible they will be met with digestive upset. The plant also contains oxalate crystals, which will cause soft tissue damage inside your cat’s mouth, throat, or stomach, causing drooling, vomiting, pain when drinking or eating, and diarrhea.

 

It’s Possible to Have Cats and Houseplants

Having cats and houseplants is possible, though it may seem daunting to those inexperienced with plant care. Once you add a new plant inside your home, chances are that your cat is dying to investigate. Keep an eye on them while they check the plant, and stop them from eating it if you can. After a while, your cat will forget about the exciting new plant, which will just be part of the decor. A great way to dissuade cats from eating your plants is to keep them high up on shelves or mantles out of your cat’s reach. Another way to keep your cat safe and healthy while avoiding boredom is to buy them cat grass or catnip plants to nibble on as they please. If you have questions regarding whether a plant is toxic, always call your vet and check the ASPCA website for its list of safe and poisonous plants.
