Why would you give your cat tylenol?
Animals bosies are physiologically very different than humans so I'd just assume that human medications were bad for animals unless specifically told by your vet that a certain type in a certain dose is OK.

Question: Hi Dr Mike:
I have a question about Acetaminophen (Tylenol?). The
Receptionist at our local veterinarian told us never to give our cats
a Tylenol? and NOT to give them ASPIRIN unless the Doctor oks it. Is that true? And what about Ibuprofen?
Answer: Acetaminophen is very toxic to cats and
this medication should simply never be used to treat a cat. Aspirin has a
long half life in cats, at least 24 to 48 hours, so it will reach toxic
levels pretty quickly if it is given more frequently than once every 48
hours and the dosage is 10mg/lb so a baby aspirin (81mg) is a much more
appropriate dosage for a cat than an adult aspirin. I have not seen much
information on ibuprofen and cats but it is a good idea to avoid all
non-steroidal anti-inflammatory medications in cats, at least until one of
them does prove to be safe in someone's clinical trials.
