i HATE this cat....

Now dont get me wrong i love cats i adore cats i have owned many many cats in my life(lets just say growing upwe were not the most responsable people when it came to having kittens i am now though) i know what kittens are like playful all over the place into everything ive owned many many many litters of kittens(again we were very irrisponsable)
so about 7 months ago my sister brings home a kitten about 13 weeks old
the kitten isnt fearful like at all but from the get go if anyone touches it tries to pet it or be nice to it it growls and begins to bite and claw not your hand but your face. if your walking thru the hosue it runs out and climbs your legs if your sitting down it climbs your back or it jumps into your lap to claw your face.
and this cat is still doing this 7 months later its now pretty much full grown. my nephew has already had to have 5 stitches from this cat and he hasnt even tried to pet the thing! hes been afraid of it since he seen it attack his mom! well now my sister decideds its his cat and its his responsability to take care of it becuase she doesnt like it. lord help me but the last time that fricken cat clawed my back i grabbed it by the neck scruff and thru at the wall i wasnt proud f what i did but ive got more scars from that cat in 7 months then my entire life! ive tried a spray bottle on it doesnt faze that cat and now its beging to pee on everythign if you scold it it looks at you and growls and hisses if you get closer it jumps at you to bite your face.
and of coarse my sister refuses to get rid of it she tells everyone how much she LOVES the cat and how she would eb devistated without it shes never been able to even pet the dang thing!!
sorry but i HATE that fricken cat that thing needs to be an outdoor only cat though i fear it would be reported as having rabies if it kept attacking people walking past....

 

im not sure what to do about this cat my sister swears up and down even to us whiles it clawing her that its the sweetest cat in the world and theres nothing wrong with it
my mom says "let her have the cat" so unfortuantly theres not much i can do unless i let it out side then like i said it will probably be taken in by animal control and tested for rabies after attacking people!
i tried letting my own cats teaching it a lesson as my own cats are elderly and dont tolerate new cats anymore but this kitten just cried and ran away to hide and my mom got angry that i was hurting it. and trust me this cat is a large cat already its a maine coon so its big and heavy which i can attest to since i have had it hanging from both my back and my legs. gets along with the dogs great though....
