New BCA (south Brazilian) Male

[Evenstar]

Congratulations!! He is very pretty! He looks like a typical curious boa. What ever you feed him, you don't want it to leave a noticeable lump. So long as you can't see it, you are good. But if a small rat doesn't leave a lump, I'd stick with those, not back down to something smaller. I'd get him back on a 2 week schedule by the time he's 2, as well, if you plan to change to 10 days.

Thanks!
I'll try a rat pup for the first feeding and see what the size is.. If it looks too small, I'll up it for the next feeding.

If you are going to feed him more often than what he's used to, I wouldn't "up" the prey size at all. A pup or weaned rat every 10 days is fine. You shouldn't see a lump. Slower is better for any boa, but BCA are more like BCC than BCI and can be a wee bit touchier with feeding. Err on the side of caution.
