Oh my goodness! How sweet! George is just an absolute love bug! There he is "working the room!"

Cats can be quite content to be "the only pet" in a household. As long as they get love and attention from you, I'm sure he would be ok. It certainly looks like he gets LOTS of love! He sure loves you! What a precious gift. However, if you do decide to get George a companion, you might consider a kitten, so he wouldn't feel as threatened as he might with another adult cat. Has he been around other cats before?
Give that lovable belly some rubbins for me!
