My 4.5 month old Terrance decided to try and get out of the cage tonight. I gently deterred him but not before he decided to nip my finger, I pulled away my hand and told him no, but alas it was to late. His teeth scratched off a bit of my nail polish when I pulled away or when he first decided to nibble. Little smart Alec. My mom paid for me to get my nails done for the holiday and he ruined my manicure I guess I'll have to be on the lookout now for the little nail biter!
