They have deeper reptile bowls too. The shallow ones are for food I think.

I prefer the Exo-Terra bowls, as they're quite heavy so they don't tip as easily when a snake gets enthusiastic. The Zoo Med bowls are good, too, and lighter weight if that's a factor (if you have to carry them very far it might be!).
