There is something fosters and cat people call "single kitten" syndrome. Young kittens without a mom or siblings tend to be mouthy and pushy because they don't get bitten or slapped back.
Gordon has an evil version of it. He is SO bitey and will slap too. Mom us trying to break the habit but he gets excited and it gets worse. He may need a friend to teach him better lessons.
He can be sweet but right now no family would adopt him. He is not gentle at all.
But he is cute.
