Cat bites to the hand can be NASTY and no hard-working postie deserves them.
Well I have a 4 inch scar on the palm of my hand given me by a rescue cat about 10 years ago. Scarred for life!
He'd had a hard upbringing, not being fed properly and treated like a toy, and would be good as gold for a while and then suddenly he'd get the claws out. He'd also take a finger in between his jaws but fortunately never bit. After we had him for a year or so he calmed down totally but hated being left alone in the house for more than a day. There'd be no damage until we got back and then he would get onto shelves right in front of us and knock stuff onto the floor. A highly intelligent cat, he was.
