Yes, it's true, and it is written in THE COMPLETE BOA CONSTRICTOR that boas grow when they are not fed.
I have confirmed this to an extent here, but I also started spring feeding.
I notice in the first picture he (Sniper) is a little pudgy in the tail or slightly above the actual tail. That is his last meal ready to be eliminated. I usually see urates first and then within a week of that he will poop.
He will lean out after that even more.
I think the next meal will be a quail probably in mid May and then I'll give him a rabbit after that. I would not be surprised if I only feed him 8-9 times this year.
Reinz,
I dig your collection. You have carpets and BC's. I can't imagine much more fun.
We still have a royal here that hasn't eaten since early November. She has eaten 3 times in the last year and has hidden the rest of the time.
My goal is a BCC and a Bredli here.
