Kitten playing too aggressively with us

It will take him (what's his name?) time to learn what is expected of him. He's just a baby, and has not grown up with a bunch of litter mates and a mama to socialize him properly.

You must be consistent. Everyone has to be on the same page. Never ever use hands or feet or any other body part to play. Always have a toy in your hand.

He is of course treating you like a sibling. A sharp ouch! and ignore is the proper technique. Hard to ignore a kitten pouncing on your ankle I know. So you may need to do some redirecting, when it is not Game time.

When he comes at you for a pounce, you can distract him by putting a toy down in front of him, before he gets to your feet. this will teach him that TOYS are fun, not feet, and will help break the habit of going after your ankles.

Carry a string on a stick, a stuffed animal he likes, or some crumpled paper balls around with you in the house, for this purpose.

During play time is when you ignore him for going after body parts instead of toys. When he latches onto your arm instead of the toy "OUCH! NO! kitty(name)" and turn your back on him. (don't shout, just speak sharply, or even a quick hiss)

Ignore for a minute or two and then resume play until he does it again. After three times in one play session get up and leave the room. Do not look back at him. Mama cats ignore their kittens to teach them.

As time goes on you will begin to learn the signs of when he is about to attack. Watch his eyes, when they fasten on your arm instead of the toy, you know what's coming. Distract him BEFORE he bites, then praise him to heaven for being distracted.

Kittens get over stimulated easily. Learning his limits, and stopping before he gets to them, will make for success.

When petting, it's the same thing. If he bites when you pet him, tell him no, and turn your back on him. Learn his over stimulation signals. Eyes wild, ears back, tail lashing, etc. Stop when you see these signs.

If you pet him three times and he attacks at the fourth stroke, stop after three strokes.

Consistency and patience are the key for successful training. Remember he is a baby and it will take him time to learn what is expected of him.
