My boy loves belly rubs, but he plays coy. He comes over and does his throaty, growling sounding meow and rubs against my leg. He'll let me rub his head, but he flops down just out of my reach and exposes his belly to me. He actually loves belly rubs too, so I don't get this out of range bit that he does! When I do manage to pick him up, he stretches out in my arms like an infant on its back, and purrs up a storm while I rub his tummy from chin to tail.
