The one pet shop I visit sometimes and also bought my female from 2 years ago always has their veiled chamelons with a portion of their tail missing. They all look very healthy and seem freindly, but I'm wondering why they do this. I haven't asked them, but will the next time I go in there. Its about an hour drive for me. The only thing I could think of why they do it is perhaps they need less calcium. I don't know just seems odd. Maybe its the breeder they get them from. I'll post a pic of my girl in the next day or two. She has a few inches missing, but other than that she is a beaut!
