Unfortunately we had just one at first. Killed adults and ducks after more came. Do not keep food out at night. Hide poison that is safe for the cats. They will die off and then any that escape will leave. Cats won’t repel much but a few mice. Rats carry disease to humans and other animals...
They climb. Trust me they run up a tree jump on roof or hit the the ground. Huge disease carrier’s. Still trying to get them out. For every one I see there are 25-50 more.
