Cat pulled out completely her nails
had my cat for 2 years now, since we adopted her she's been fine, very sociable and everything fine, she's about 2 years and half, and she's and indoor cat. A couple of days ago I found blood and fur on the computer table, I checked and it seemed that she accidentally had pulled back one of her nails. Later on I couldn't see her claws when she was stretching, I checked her back paws and she has no nails in her two middle fingers of each of her back paws, only raw flesh, so I guess that if it was 4 nails, 2 in each paw, she pulled them out herself?. I am very frustrated with this, I don't understand why she would do that to herself, obviously it was painful and now she's very sore; she usually chews her nails in the past, and I know that's O.K., but has someone else seen their cats pulling their nails out before? She's not bleeding anymore, but still it's very sore and gooie, I guess I will take her to the vet just in case of an infection.
Any suggestion of why?
