Bloated Sand Boa

[Bogertophis]

The weakness is new. He was normal when I fed him on Sunday (10 days ago). The weakness and bloating seemed to come at the same time when I checked in on him last Thursday (4 days post rat)

He's not been dropped or pinched in his tub. He shouldn't have over heated; his basking spot is regulated with a thermostat.

I'm still weirded out by the possibility of IBD. Though none of the other snakes in quarantine are showing symptoms... The vet seemed to think that it was a low probability, and he's only ever seen 2 cases himself.

I agree with your vet...IBD is very unlikely. You can't rule it out based on your other snakes showing no symptoms though, as all snakes don't progress with the illness at the same pace. Maybe he just had a 'tummy ache'? I really hope he gets back to normal.
