Hobbes absolutely loves belly rubs. He will be sound asleep, but as soon as he feels your hand touch his fur; he will kickstand a leg up and encourage you to continue.
He is the sweetest and is very much a lap cat. As I told a friend we had over once, put the blanket in your lap and you have a cat.
Calvin and Hobbes while very similar in demeanor are very different. Calvin has an attitude and knows more than his hoomans (or at least thinks he does) whereas Hobbes is very chill unless you have Tillamook on your plate.
