Cats LOVE to lay under the tortoise's indoor lights (and maybe use the substrate for their daily ablutions)
Maybe if they are raised together it would get them to not fight?
What do you mean “raised together”? Are you trying to permanently House a cat with a tortoise?
If you put a kitten with a hatchling, it would most definitely be harmed.
You should never purposely put another animals with a tortoise(unless for a bioactive enclosure).
I agree I’m just thinking super long term my boyfriend was wanting a cat but I’m in the process of building a tortoise farm so just thought I’d hear some feed back now.
