Kippy used to love being petted anywhere. Now that he's gone I realize how special he was and how much I took him for granted.
Cinder and Laelia like to be petted on their bellies, but only if they initiate contact.
Toothless is pretty tolerant but only likes so much belly petting.
Snickers LOVES having his head rubbed and his back is a safe zone, but don't go anywhere near his belly or paws. And he HATES feet so much that just walking past him can be dangerous.
I forgot this one. When he's in the mood I will tickle his hind paws and he spreads them out really wide for me to do so and being a MC they go really big.
