My two sleep in my kitchen as Huly sleeps with me. I wake up with paws in my face and I know it would be a disaster if I tried to sleep with all three.
It is really funny as I can see Huly wants to play at times with Sonny and Sonny tries to play with Huly at times but they just haven't figured out how yet. BG stays away from Huly or goes to flat out (laying down not moving) when he is near. She was the first and respects Huly and probably a little scared of him as she met his paw a couple of times. I threatened Huly that if he hit hurt again he would not have any midnight snacks and since then he only tries to trip her.
Huly is declawed (my other rescue cat was declawed when I got her so only fair I had it done to Huly) but him and my husband has play boxed their entire life so his paws are so strong. He is 11lbs but STRONG. I worried that 1 good hit from his paw could seriously injure the chis when they were pups. Now BG is still more delicate but Sonny is Mr rough and tough and if he can rumble with Gibbs (55lb basset) he can handle Huly. He still noes not show Huly respect but hopefully one day they can work it out and play together as I know both would have a blast playing with each other.
