Almost 4 months old.
The bite, then twist and rip has completely ended.
The bites are turning into nibbles and getting softer.
The squirming and wriggling to get loose is happening less when picked up.
AND, I just got 10 minutes of snuggles, purs, baby pats with no claws, and licks with no teeth.
It's a new record!!
SO, there is a light at the end of the tunnel.
He plays VIOLENTLY. Simply resist the urge to hold or pet when he's playing. Stuffed toys I hold up and he stalks, pounces, and attacks them. I just let go of the toy as soon as, or before, he hits them.
If he's searching for something to attack? I just be very still (hands, fingers, toes...don't move).
And I make sure I don't TOUCH him when he's wound up because that just adds fuel to the fire.
When he's calm, I get a couple of minutes of petting and holding niceness, several times a day. Just not while playing.
Any mishaps are met with a "NO!"...and I either leave his room immediately, or take him to his room immediately.
He'll continue to get better as he gets older.
We have a 4 year old named "Squirms". This because you couldn't hang onto her when she was a kitten. It was like holding running water.
Now, her favorite place is a lap, or in your arms going for a people ride.
Kittens will outgrow that crazy attack/bite stage.
SO, for those of you with insane kittens? It will get better.
