They love soaking. I know a good guy who owns a really nice exotics store, and they have a blood there. The thing soaks in a kitty litter box quite often. It's definitely a good idea to give him something to soak in, though the soaking with an open wound worries me. I'd ask your vet friend if its okay for it to get wet, or has it healed up pretty well? IMO you should call him up to just double check that giving him a soaking bowl wouldn't cause a huge jump in probability of infection.
Again, it's really awesome what you are doing. Keep us updated on how hes doing!![]()
