If your Sylvester is a fairly new addition, the cats may just need to get used to each other. They may or may not become best friends but when they are ready to play or sleep and no one else is available (namely the humans) they will seek each other out. If you do not know why Sylvester's face is deformed it would be good to find out. It may need monitoring. It may affect balance but so could the fact that he is declawed. Of corse he may just be "klutzy". Instead of bringing him to you, I'd go to him. He most likely feels most comfortable where he chooses to stay and maybe he just likes time alone. When I have a new cat that prefers to stay in one room (this was usually because there were afraid or shy) I would keep them company in that room and slowly move furhter and further out of the room hoping they would follow. Keep us posted.
