Rat Toy Ideas. I want to make a city out of cardboard boxes that I can use during playtime. I think they'd have a blast with it.
I do playtime either on the couch or on my bed. I just remove the covers from my bed and add an old fleece blanket bunched up in one area, a couple baskets/large bowls, some pvc pipe tunnels and then add me and the rats. I do separate play times for the girls and for the boys. They occasionally pee on the bed but they have never left poo on the bed and they rarely ever accept treats/food when they are out of their cage.
They do love running all over and exploring. That's why I think the idea of a rat city of boxes would be neat.
