I love rats, have kept rats as pets, will keep rats as pets again someday. The only way to solve this issue for the building is to kill them, because they’re so sociable and smart amongst themselves. They breed faster than rabbits, and the teach each other, and fend for each other. They over-Wintered last year. They’re stuck in. I think I need to find a new shop.
@DubleveWands I think you do need to find a new place. You may get a break in between, but this. But someday some will come back. I wish you the best of luck with all that mess. I am sorry.
