What is the safes to give to cats baby aspirin?

A cat's body is much different than a dog or person. The smallest amount of a drug will stay in their bodies for a long time and they can easily overdose. It is not safe to give your cats any drugs, without talking to a veterinarian. I took my cat to the vet a couple of weeks ago, because she seemed to be having some pain in her hips (she's old) and I specifically asked if we could give her aspirin or tylenol. She said NO.
