I have posted before when our newbie was 3 months old about the fact that this new kitten was terrorizing the 2 eight yrs old and have tried EVERYTHING I know, using many tips you folks have given us. Ok now he is 6 months and still just brutally running full force to his older bros and attacking them, the grabbing him by his scruff and re-directing has worn off. I still do it and usually get bit as he hangs on for dear life. My concern (and guilt feelings) is how my older cats are taking this behavior from him and growling, hissing and hiding. I am staying calm as possible but I see their lives have changed and not in a good way. I find wads of fur from these fights after being gone a few hours. I do realize he is still a kitten, but in all my cat experience over the years, have never had a "kitten" bite hard and completely ignore all my attempts to re-direct or step in the minute I see him about to pounce. I guess I am just hoping someone knows of some New way to handle this!
