We have a lovely tabby cat aged 8. When we first got him he was about 1 and a rescue cat. At that time he could be quite aggresive but this gradually settled down and now he is very calm with me and great with our 2 dc. However, he has continued to attack my dh despite his best efforts to get the cat to like him. The cat also sits in my dh's usual place when he is at work. Is there anything to be done to improve their relationship?
