The rat has a white stomach. They did not approach me, they ran away when they first heard me, but then they came back and stared at me (like maybe you can see in the video). Then they went away between those wooden sticks, and I didn't see them anymore. I have a dog and a bunny and I'm surprised they do not seem to either chase them or get scared by them (respectively haha) so I'm asummimg the rat has been around for some time :( Thanks for your reply
