No we all now that the belly is very sensitive spot for a cat. Non-owners don't see to get that, I had a friends who would always said 'I tried to tickle his tummy and he tried to bite my hand off', to which I would always reply, 'well he's not a dog', after this she always went off in a huff because she had no understanding of animals whatsoever. My MIL who used to bred cats told me that if a cats lets you touch their belly its a sign of complete trust which is nice, but i think in some cases cats just don't like it. Frank after a while would let me stoke his belly but only me and it was only after few years of living with us, Max never let anyone touch his belly even me, we'd be lying in bed and i'd stroke his back or his head, he even let me stoke his paws, but if i even strayed too close this belly the claws would come out. Do any of your cats let you touch there belly do you think it is soley a trust thing?
