Hi, I have posted here before about my kitten. I have another question. My kitten is 6 weeks old and is a boy. He is the only pet we have in the house. We when first got him he was very well behaved, but now he is very aggressive with us. He keeps biting our fingers, legs, toes, and clothes. We have tried bitter apple, we have tried spraying him with water each time he bits, and we have tried buying him lots of toys to let him bit on. Yet all he does is lick off the bitter apple from our fingers and continue to bit. What should we do?
