Guide to US plants poisonous to cats

You might think that with cats being obligate carnivores they wouldn’t be too interested in grass, or plants, or anything green for that matter.

Well as you probably know by now, that innate feline curiosity means we should rarely try and second guess what our cats are thinking. 

Leave a plant within touching distance of them for instance, and don’t be surprised if the next time you come to water it, there’s a bite-sized chunk taken out of it. 

The problem with this is that a large number of plants and flowers can be extremely harmful to cats and they have no idea which ones are safe or not. 

That’s why Reveal has put together this handy guide so pet parents know which plants are poisonous and which are perfectly safe.

What to do if your cat eats a poisonous plant

  • Stay calm. Stop your cat from ingesting any more of the plant, while attempting to remove any pieces from their mouth or fur. Move them to a safe space, and ensure the plant(s) cannot be touched by any other pets.
  • Check for symptoms. Breathing difficulties, drooling, vomiting, diarrhea, and an irregular heartbeat are all symptoms associated with the ingestion of a poisonous plant. You may also notice redness and/or itchiness of the skin or mouth.
  • Contact your vet. You should ring your vet immediately if you suspect your feline has eaten a toxic plant, even if they are not exhibiting any symptoms. Explain to them what has happened, and await further instruction.
  • Bring samples with you. If the vet wishes to see your cat, make them as comfortable as possible before setting off. If you don't know the name of the plant they have eaten, take a piece of it with you. Also, if your cat has vomited, collect a sample of this to hand over to the vet as well.

Should I keep plants out of my house?

This article hasn’t been written to put you off filling up your home with leafy houseplants. We love pets and plants.

All we are asking you to do is proceed with caution.

When buying a plant for the house, do your research, and if you’re still unsure, seek medical assistance. If you’re moving into a new house, carry out a thorough examination of the garden before letting your furry friend outside. 

Even if a plant isn’t classed as being harmful to cats, it’s still not a good idea to just let them nibble away. Maybe keep your greenery in a room that’s inaccessible to your feline, or place plants somewhere high up, out of reach.
