They should. They are brothers all the same age. Curly is the most active. Loves running in the wheel. He is so comfortable in his own place that I catch him sometimes sleeping in the open. The only side effect is that they smell a little. One probably won't smell as bas but 2. All 3 are in separate cages. They started squabbling so it was time to separate. I think they are about 7 weeks old at least. Their other brothers and sisters went to a new home at Things That Squeak in Akron OH. All the girls were pregnant. I got them from irresponsible person at work. I actually wanted to keep 2 but Curly hid in the bedding. I guess he wanted to come home with me.
