What plants are poisonous to cats? Find out more about toxic plants and flowers in our expert guide.

Cats and poisonous flowers and plants

While it is common knowledge that lilies (all parts of the plant) are poisonous to cats, many other plants can be dangerous if eaten. Watch our video, featuring our expert vet Alison, as she meets a florist to discuss the dangers that some flowers pose to our feline friends.

Why are lilies dangerous to cats?

Lilies are particularly toxic to cats. Although you might find that your cat is disinterested in eating them, there is always a risk that they may come into contact with the flower's pollen by rubbing up against it and absent-mindedly licking their fur.

Unfortunately there are several types of lilies that are poisonous to cats, including Easter Lily, Tiger Lily and other members of the lily family. If you're not sure what these look like, take a look at our visual guides below.

All parts of the lily plant are toxic to cats if ingested, and consuming small amounts can result in severe poisoning. If you're concerned, the best way to prevent your cat from being poisoned is simply to not have lilies plants in your home or garden.

Keeping your cat safe from dangerous plants

Cats are usually careful about what they eat. However, sometimes young, inquisitive or bored cats may nibble on a plant that makes them sick. They can also unintentionally ingest poisonous pollen or plant matter when grooming themselves.

Does your cat like to eat grass or plants? You could grow cat-friendly plants like catnip, mint, cat thyme and lavender to encourage them to nibble non-toxic plants in the garden. When gardening, clear away clippings as these may intrigue curious cats.

If you suspect your cat has eaten a poisonous plant, contact your vet immediately. Don't wait for signs of illness to appear as by then it could be too late.

Which flowers are toxic to cats?

Whether you're choosing beautiful blooms for a bouquet or wondering what indoor plants to get, you'll need to be wary of the flowers that are hazardous to your cat. Common blooms like lilies, poppies and marigolds can be harmful as well as seasonal plants like mistletoe and poinsettia.

The Great Outdoors

If you're a keen gardener, you might be concerned about the outdoor plants that you are planting. While most cats will instinctively avoid eating things that are bad for them, it is worth being aware of the outdoor plants that are toxic to cats.

If your cat spends a lot of its time outside, it may brush against plants and lick the pollen off without even thinking. 

For more information on outdoor plants that may be dangerous, take a look at our visual guide or comprehensive list below.

What are the signs of plant poisoning in my cat?

If you think your cat has been poisoned, contact your vet immediately. Don't wait for signs of illness to develop.

Signs of poisoning can include (but are not limited to)

  • salivation
  • vomiting
  • diarrhoea
  • twitching
  • fitting
  • breathing difficulties
  • shock

First aid for poisoned cats

If you can see the poisonous substance, take your cat away from it and then call your vet for advice. They may want to see your cat immediately. Making your cat sick may not be helpful.

If you have evidence of what your cat has eaten, take a sample to the vet. Even a sample of vomit may help diagnosis, particularly if it is an unusual colour or contains plant matter.

Most importantly, don't panic. Seek advice from your vet immediately and they'll be able to help.
