Trim the claws - yes! - if those pills had really knocked out Tommy, just a bit more, I might have trimmed his claws. Tommy was old and tough when we rescued him from a horse barn, covered in fleas, sneezing black matter, and my husband was in shock and awe that I had salvage this creature from the death pile. Tommy has two good years with us in spite of his derelict condition. He had to put be put down when he was no longer able to stand or drink water or eat. Tommy! The old ginger tom. The Man. The cattest of all cats.
