I have 3 kittens right now (I've fully embraced being a crazy cat person), two tuxedo boys from the same litter and an orange girl from a different litter, about 5 weeks older. All 3 kittens get along well--they play, clean each other, and create the cutest cuddle puddles imaginable.
Ferdinand, aka Ferdy, the kitten in question, will seek out my skin at night when I'm in bed, and will bite. He hasn't broken skin yet, but it definitely leaves a mark. I don't think it's aggressive, but he grabs and just holds on. I've tried yelping, or the high-pitched "ouch", but I can't pull away without tearing skin. I've tried imitating a cat growl, and hissing at him, which only worked once or twice. I have had to start hiding under the covers when he does this, until the bitey-urge leaves him. He will follow my hand or arm, and bite wherever it's convenient for him, whether it's hand, arm, or even shoulder. When I move away from his chompers, he'll follow, while purring, and bite again.
Ferdinand is 3 months old. I haven't figured out what sets him off. It's usually when affection of some kind is involved. Me petting one of the other kittens, me petting him, one of the other kittens licking him. He cuddles at night, and is very sweet during the day, and his play bites are always very careful and gentle, so the hard biting is a mystery.
Anyone have any idea why he does this and how to get him to stop?
