Cats are carnivores and usually do not eat plants. On occasion a cat might eat grass because it instinctively knows that grass will make it vomit. Cats sometimes chew grass if they have an upset stomach, worms, or hairball they are trying to bring up. It is rare that a cat will chew on any other garden plants and as such there is very little risk of them being poisoned from any other plant than certain species of lily.
Lilies are really the biggest risk to cats. The risk is not of the cat eating the plant, but of the cat walking near the plant, or brushing up against it. While the entire lily is poisonous to cats, the risk is the pollen. Cats generally wont eat lilies, but if they have pollen fall on their fur they will ingest it while grooming, and as such will consume the toxic pollen in that manner.
Symptoms of Lily Poisoning (cats may have all or some symptoms):
- Refusing to eat
- Breathing problems
- Paws and/or face swell
- Kidney problems; renal failure
What to do if Your Cat has Ingested Lily PollenChances are you won’t know your cat has ingested lily pollen until symptoms show up. By that time it is urgent you get your cat to the veterinarian. The vet will work to reduce the toxic effects of the lily pollen, often by forcing the cat to eat activated charcoal, and by putting the cat on an IV to aid its kidneys. Note that kidney failure is often the main cause of death for cats that have ingested lily pollen.
If you happen to catch your cat immediately after ingesting lily pollen (such as if our notice your kitten chewing on the lily flower as playful kittens may be apt to do) you should call your veterinarian immediately in regards to inducing vomiting and the kitten should be taken to the veterinarian to reverse any ill affects from what poison may have gotten in its system.
