He also enjoys looking out the big window and knocking things off of shelves.

Shiro is deaf so needs an adopter who will work with that.

Shiro is a very high energy cat. A playmate would be good because he gets bored easily, but they would have to be young. A very young cat would not be as threatening to him and would have the energy and playfulness to keep up with him.

He’s very afraid of any amount of water larger than a normal bowl.

Wand toys are his absolute favorite. He drags them around by their feathers or the toy at the end of the string and it is very cute.

He’s not much of a lap cat so far, but sometimes he chooses to snuggle and I know, in his own house with his own person, he would grow to love snuggling and demand it.
