The Pet Place Veterinarians suggest:

General Information. There is not much you can do at home for most poisoning. Call or visit your veterinarian or veterinary emergency facility if you think your pet has been poisoned. For some ingested poisons, your veterinarian may recommend inducing vomiting before bringing the pet in for examination and treatment. Inducing vomiting of a toxic substance should never be done unless specifically directed by a veterinarian. For topical exposures, bathing in lukewarm water with a mild dish soap can reduce further toxin absorption before the pet is examined and treated by a veterinarian.

Following is the second in a series of an abbreviated ABC listing of common cat poisoning item discussions. Please refer to the complete article for an expanded version to help you with your cat health concerns.

Remember, always be sure to keep all poisoning medications out of your cat's reach and keep trash cans covered.
