Never give acetaminophen to a cat or dog. In cats the drug affects oxygen in the blood, and it produces severe depression and abdominal pain in dogs. If not quickly eliminated from the body, just two extra-strength tablets in 24 hours will most likely kill a small pet. Clinical signs in cats develop within one or two hours and include excessive salivation, paw and facial swelling, depression, and ash-gray gums. In dogs watch for anorexia, vomiting, depression, and abdominal pain.
High doses are usually fatal.
Garbage is not often regarded as poisonous. After all, many animals find compost attractive. But toxins are produced by bacteria fermenting the garbage. Rapid and severe signs include vomiting, bloody diarrhea, painful abdominal distention, shivering, shock, and collapse. Make sure the lids are tight, the containers undamaged.
