Bruised Claws?

I didn't know that it was possible for a cat to bruise it's claws.

Hubby put Darcy in her crate while the flea spray on the carpet was drying (this was Thursday). Darcy hates being enclosed so if he were to simply have shut her in the utility room, she would scratch the door - or worse (we have found her tangled up in the blinds on top of the window trying to get out). So I asked that she be put in her little crate so she wouldn't damage the doors or walls or blinds. She spent the whole hour digging at her crate. Well, I went to trim her claws today and they are all brown and purple and red...like bruises. Her back claws look normal.

Anyone else with this experience?

I have a cat who absolutely hates being in a crate. He scratches and bites at the door the whole time he's in there and always injures himself. I finally ordered one of these so he won't hurt himself the next time I have to take him to the Vet. http://www.livetrap.com/cgi/search.c...al+Cat+Handler

If there is someone nearby, she won't scratch. If we take her to the vet, she doesn't scratch. I think it is the act of leaving her alone in an enclosed space that drives her crazy...she has never gone to the point of bruising her claws before
