I think my bunny Fred is chewing some of his nails. When I go to trim them, some are sharp and pointy with lots of scratches on them. If I try to trim off the sharp point, he pulls his foot away. I think it's because he has chewed them down really close to the quick. There was one I noticed today that even looks split down the middle. Some of his nails look normal and I am able to trim those without him protesting. I am wondering if there is a way to stop him from chewing his nails so I can trim them and they aren't so sharp.
