The first time that we gave Lamoni any nip he got sooo stoned that he could hardly walk. I pointed my finger at his nose and then quickly pointed to the ceiling. He raised his head to follow my finger and fell over.

My old vet warned me about nip. Don't give it to cats that are going to breed. High probability of birth defects. But after you nip the cat at one end you can nip them at the other.
