I adopted my cat Oreo from a no kill shelter last November at the age of 6 weeks, he was very sweet, gentle and loved to play but as the months have passed and he has grown he has become very aggressive and mean to the point of biting, scratching and attacking my boyfriend and I out of nowhere and when we try to discipline (spraying water, time outs or even just going to pick him up to sternely tell him to stop it, he purposely bites at our faces. Both my boyfriend and I love our cat and he can be very sweet sometimes but the majority of the time is spent punishing him for doing these things and its breaking my heart because it isnt doing any good and I hate disciplining him. He just seems to get worse, he is now not only attacking us but the furniture, curtains, anything he can get his paws on or his in his mouth. Its scaring me because Im starting to think something is wrong with him. Please help!
