All 3 of mine (3.5 lb, 6 lb 6.5 lb) sleep with us and have been since they were 12 weeks old. We do have stairs that they use but have had no problems in the past 2 years. We also have a cat. He did not like them at first but they get along fine now. The cat will either get used to them and start playing (mine does) or he will just stay away from them. |
