Tylenol is extremely toxic to cats and can kill them quickly even if it’s given in small doses. You should never give your pets any medication without the advice of your vet. Acetaminophen  is the active ingredient in Tylenol. It’s an over the counter fever reducer and pain reliever. Cats lack an enzyme in their body that a metabolizes acetaminophen. Therefore this leads to severe damage to your cats red blood cells, liver and kidneys. Dogs also do not metabolize this drug as well as people and only your vet can recommend the dosage to give a dog. Never do it yourself!  Dogs can die of an overdose as well. The side effects of Tylenol in a cat can range from vomiting and diarrhea to severe anemia and liver failure.  A muddy brown color to your cat or dogs gums can indicate the effect of Tylenol. Poor oxygen-carrying capacity of the red blood cells can cause this. Liver damage can result in jaundice and a yellowish tinge to the mucus membranes of the skin.

Never leave Tylenol in a pets reach. A little precaution is worth a lot.

Remember, your pets count!
