i know people usually say that cats and dogs could hurt tortoises, however my cats have all been raised along side randall and have NEVER made any attempt to injure him. they are also ALWAYS supervised. most of the time they could care less about him walking around the house.
you do know that torts eat hair? it will accumulate in the gut eventually killing them, please do make sure no hair is eaten i knew of a russian that died after five years of hair eating, autopsy showed.
