This ^ ^ ^ ^ ^ exactly.
When my BCI was full-grown, her stool was comparable to something my bigger dog does, & her urates were solids, not runny. She was far more pleasant to clean up after than any retic would be.
Seriously, do consider how long you'll enjoy being a slave to cleaning up after a large messy snake before you begin to resent it & wish you'd taken another road. Boas, like the BCI I had, eat about every 2 or even 3 weeks when fully-grown & older. And with the temperament being far more conducive to handling- boas just make far better pets if you want a large snake. Also, when you need vet care, your vet would MUCH rather deal with your boa, & might charge accordingly.![]()
