Can he breathe?

Just moved my BP into his new tub, I drilled around the tub. but only the top, not the bottom, and I drilled 2 holes in the top. Is he able to breathe well?

Short answer, yes.

If you are concerned, drill more holes :)

Thank you for the fast response and short answer :)

Don't drill any holes within an inch of the bottom, otherwise you could have a mess dripping out with liquid urates or if he spills his water dish. Also a soldering iron makes a cleaner hole with smoother edges. I generally only put holes in the front and back of the tubs.
