We only have one in our home, it was going to be discarded by someone so we took it, I really didn't expect it to survive long since we had never owned one before, but here we are 5 yrs later & he's still here...
A couple of years ago we thought he was lonely and he needed a friend, so we bought one for him...the next day he was all alone again

.....I don't think he'll be getting another friend....
