I feel that they are. I don't know for sure, but if i were to be gone a lot i would feel bad if i only had one to leave it by itself, i would feel it would get real lonely. If the person is always at home with it then i think it would be okay and not feel as lonely. I have 3 and they play a tons and seem really happy and close. When im not here i know they play and get into all sorts of things together, they seem much more content that way |
