You should have got 2 of them !!!
The ones I have ....they have 2 totally different personalities.
Sasha is more of the lap dog attention whore while Mimi is the shy one.
They've bonded with the wife very strongly becuase she spends the most time with them.
I think they shy away because they are intimidated with our size and there only a few pounds.
I usually lay on the floor with them for a while each night when I get home....they don't shy away then !
When they play/fight it sounds so vicious but a lot of it is just chatter.
But when you pick them up they turn into lambs *l
And if you have recently fed them and you call them over to pet them but you don't have any more food to hand them then they don't want anything to do with you until this feeding coma goes away
As far as the training goes we used a reg size littler box like you'd use for cats with just newspaper lining it.
Take one of their crayon size turds and put it in there.Of course you want to monitor them closely and try to catch them thinking about peeing somewhere else then quickly grab them and put them in the box.
Because ours are now about 4 pounds each we got a bigger litter box.We bought one of those plastic under the bed storage containers...its about 3 feet long and a foot wide....maybe 6 inches deep....cut a small entry way in the side...line it with newspapers...I like to use the sports section when theres pics of the yankees on it.
