The quickest way to make friends with a cat is to scratch it behind the ears. The big question is why do cats enjoy this simple act instead of enjoying being scratched on other parts of their body?
Dr. Nicholas Dodman, a professor at the Cummings School of Veterinary Medicine at Tufts University, thinks it’s because cats can’t touch the tops of their heads with their paws, and it’s impossible for them to lick it with their tongues.
Head scratches could also remind cats of their mothers who likely licked and groomed the tops of their heads when they were kittens. No matter what the reason, take a moment now to scratch your cat on the head. Your cat will likely thank you for it by ignoring you and treating you with contempt.
