Beyond control it seems

Hi and welcome to the Forums!

What a problem!  Cats playfully attacking isnt that unusual. But attacking for real?  Rare.

Yet, everything cant be bad as your bf loves him, right?

How old is he, is he neutered?

Is there something which may stress him?  Some peculiar noise or vibrations from outside?

Or smells or looks from other cats from outside??

Such aggressive attacks on the owner are not uncommon if, say, the cat sees a foreign cat outside "in the revire".  And as he cant reach the foreign cat, he moves the aggression on what he CAN reach. It may be his cat pal, or the owner...  In such case it doesnt helps with punishment, it is only to lock it in a room for himself several hours, so he or she can cool down...

And of course, make so he doesnt need to see or smell this foreign cat anymore.

Do neuter if he isnt neutered yet.

How is his health?  Cats with pains have lesser patience than usual, and thus, are quick to teach lessons.  So a visit to a good vet is recommendable.

You can also try with a Feliway adapter. Which will hopefully make the cat feels safer and more harmonius.

For the dog there is something similiar, its called DAP.

Both entirely non dangerous and quite natural.   Although not vere cheap.

Good luck!   *vibes*

Agree with above....how old is he?  It is perfectly natural for a kitten to attack and be overly playful.  Just give a bit more info so we can be of more help.

If he's a young kitten, this is all normal behavior.  Possibly getting him a friend will help with the aggression.  They can learn proper behavior together!

Also, what types of "punishment" have you tried?  Do you have wand toys like daBird or a laser pointer?  These are great for entertaining a kitty as well as working off the excess energy they have.

Oh my gosh, he's just a baby!!  All of this behavior is totally normal!  Most of the time during this stage, his mom & siblings are teaching him manners.  Now it's up to you.  (A kitty of similar age would help him tremendously, if possible.)  You can hiss at him, just like a momma cat would do.  You can also put some dry beans in an empty soda can sealed off with tape.  Rattle it when he's doing something you don't want.  Also, distract him with toys when he's doing undesirable behavior.

Right, agreeing with Stephanie and the others.  My analysis was mostly for grown up cats, who do defend their revire or have need to teach.

But here we do have a little kitten.

Kittens do plays a lot, and many of the plays are quite vigorous "attacks" and wrestling matches.  Normally he would do it on his siblings, or biting his ma´s tail.  (or biting on dads tail, if they live in a family group, for example with a breeder).

And these siblings and his ma would teach him to not to overdo the attacks, by shrieking and by hissing.

Here he hasnt no siblings, so it is only his owner to play with and to "attack"...  So do shriek and hiss you too when it begins to hurt.  :)

Lotsa play, and as said, consider to get him a pal.  Kitten or perhaps even better, a friendly adult.  A friendly adult will also learn him cat manners.

You know he is really too young to be taken from ma and siblings...   Rescuers do often such by dire necessity, but rescuers usually do have resident cats or other kittens who held them company.

This is our advice.

Good luck!  *vibes*
