My veiled chameleon is about nine months old. She has been very healthy since I got her in June. Her nails became very long and sharp and remained this way for months. I recently noticed that some of them seem to have broken off. The ones that have broken all seem to be on the outside-facing toes. I was slightly worried when I noticed, however I am now more worried because I believe that she is losing her grip because of this. I saw her fall off one of the highest branches the other day and I am now quite concerned. Should I be? She seems to be eating and drinking as always and has a daily supply of calcium dusted food as well as a UVA/UVB heat lamp. Is this a problem?
