I have recently rescued a RTB who is about 5 years old & about 3 and 1/2 feet... He is a male. I am really hoping & wondering if his size will increase much if I feed him weekly. The previous owner wasn't on top of feeding as much as preferred.. But he is now on large rats & takes them happily. Does anybody know if his lack of food has lead to stunted growth & can this be reversed?? Thanks!
