Houseplants that are poisonous to cats

Every year, thousands of cats are poisoned by houseplants. Some plants are more poisonous than others, and some can even be deadly. If you have a cat, it’s important to know which plants are safe and which ones to avoid. In this article, we’ll discuss some of the most common houseplants that are poisonous to cats.


The entire lily plant is poisonous to cats, including the bulb, leaf, flower, and stem. All parts of the plant contain calcium oxalate crystals, which can cause irritation in your cat’s mouth and throat. Eating just a small amount can cause serious health problems, including vomiting, difficulty breathing, and kidney failure.

Aloe vera

Although the gel from aloe vera plants can be soothing for minor cuts and burns on humans, it is poisonous to cats. All parts of the plant contain aloin, which is a laxative. When ingested, this substance can cause vomiting, diarrhea, and tremors in cats. If your cat ingests any part of an aloe vera plant, call your veterinarian immediately.

Sago palm

All parts of the sago palm are poisonous to cats, but the seeds (or “nuts”) contain the largest amount of cycasin, which is the toxic compound. Just one or two seeds can cause severe liver damage in a cat. The plant’s leaves are also quite poisonous. If a cat ingests even a small amount of sago palm, it can cause vomiting, diarrhea, bruising and bleeding, liver damage, and even death.

Houseplants that are safe for cats

Most cats enjoy nibbling on grass, and many houseplants are harmless if consumed in small quantities. nibbling on grass can help them with digestion and may even help to settle an upset stomach. plaintain, wheat grass, and catnip are all safe for cats to eat.

Spider plant

(Listed as non-toxic to cats by the ASPCA)

The spider plant is a popular houseplant that is known for its ability to tolerate a wide range of growing conditions. It is also one of the few houseplants that is safe for cats, making it a great option for homes with pets. Spider plants are low-maintenance plants that can be easily propagated from cuttings, making them an ideal choice for busy pet parents.


While catnip (Nepeta cataria) is non-toxic to cats, not all felines will respond to it in the same way. In fact, some cats may not react to it at all. For cats that do enjoy catnip, it can serve as a mild sedative or stimulant, depending on how much is consumed. It’s also worth noting that catnip is a member of the mint family, so it has a strong scent that some people find overwhelming. If you grow catnip indoors, you may want to keep it in a pot so you can control its spread.


Rosemary (Rosmarinus officinalis) is an evergreen shrub that is part of the mint family. It is a popular culinary herb, but can also be used as a decoration. Rosemary is native to the Mediterranean and has long been associated with memory.

This plant is safe for cats and can actually be beneficial for their health. Rosemary contains antioxidants and can help boost the immune system. It can also help improve digestion and relieve flatulence.
