Thanks, everyone! She started out pretty standard looking, but I'm really liking the lighter colors she's getting. I'll have to measure her again, but she was over five feet a few months ago. I'm hoping her colors will continue to stay light like this, but she's pretty when she's dark too.
She was a pet store boa, so I don't know a lot about her. She was sold as an "aberrant RTB", but as far as I know, she is just a normal. Thanks!
