On a thread many months ago, I was asking for opinions about what to do about Connor's habit of chewing his fingernails off (and toenails ). In the end, I decided to just let him chew them after talking to his doctor about it and getting your advice online. So thank you! I'm happy to report that Connor has decided to stop chewing his nails, and they grew so long that I had to clip them last night . He said that the metal against his skin irritates him (from the clippers), so next time I'll file them down. I have no idea why he decided to stop chewing them, but I was so happy to see his intact fingernails this weekend. Yeah for Connor!
