I have an enclosure that’s a modified dog house with heat, lights, food and water. It’s been pouring raining and the last two days I noticed a little rat hanging out in the enclosure. The enclosure is 40.8 X 26 X 27.6 Inch and Scooter is a little larger than the diameter of a softball. The rat and Scooter rest next to each other. There seems to be zero aggression and they actually look like they accept each other. Scooter lays down with his head completely out and legs and arms sprawled out like he’s on vacation and the rat lays next to him. I’m concerned that the rat will eventually turn on him and bite him. Is this a known problem or can a rat and a tortoise cohabitate?
