Mr Claude has adopted us! We've had him for nearly a year now. He was not neutered and could be aggressive now and again. Since we've had him neutered (he is 18 months old approx) it's got a lot worse. Our other cat who has impaired eyesight, hearing & smell lives in fear as he is constantly attacking, stalking & bullying her. He never did this before he was neutered. I've put a bell on his collar so she has some kind of warning . He also attacks me and my partner for no apparent reason. He can be purring one minute, then the next he's clawing and biting really hard. 9 /10-times he draws blood. He's even bitten me on the face while I was in bed asleep! Now it's a constant battle , I have to escort our other cat around the house because of these attacks, we try to keep them separate as often as possible but sometimes its just not. We are thinking of giving him up for adoption. I can't bear to see our other cat in distress. We're both stressed about the situation too. Help!
