Plants Poisonous for Cats

THE NUMBER ONE CAT KILLER IS THE LILY (all types).  It is by far the most dangerous and deadly plant for cats.  The whole plant is toxic and can and does kill.    There is no antidote. The cat should be taken to the vet immediately it shows any symptoms,  although a vet can only give intensive supportive care the best course of action is prevention.  If the pollen from a Lily falls on a cats fur, and the cat then licks his coat and digests the pollen it could well die a horrible death.  If you have to have cut Lilies in the house cut the stamens out and don't have them in your garden.

The next poisonous plant is the Poinsettia.

The next is the Hydrangea.

Then the Cyclamen, the Cordyline, the Carnation, the peppermint plant, the Clematis, Ivy, the Lupin, the Peony, Poppies, Rhododendrons
and Cotoneaster .

There are some 140 poisonous plants for cats. 

Slug killers and some weed killers are toxic, always read the instructions and advice on the labels, and keep them well away from pets.

Signs of poisoning:
Convulsions, hypersensitivity, temperature changes, repeated vomiting, dribbling and skin irritation or swelling.  Signs tend to suddenly appear.

What to do if you suspect your cat has been poisoned.

Speed is essential so phone your vet for advice.  Making your cat vomit is not necessarily the best course of action.
Look for evidence of what the cat has eaten, such as a knocked over vase of flowers, or half chewed packet of pills, flowers, or plant roots. Take the evidence, and even a sample of the vomit can help, particularly if it has plant matter in it or is an usual colour .
If in doubt get to a vet quickly.

Given a good source of grass most cats will ignore other plants, but the LILY can kill just by the cat brushing against it and taking the pollen onto its coat.
