Please please please, I hope someone can help! I got two female kittens two and a half years ago. When they were 18 months old I introducted two male kittens. I followed the steps to introduce them, i.e. kept them in their own room, scented them etc. There was some hissing and the girls didn't like the boys but it did seem that they were tolerating each other. The girls are now 2 and a half years old and the boys 1 year younger, and the boys have driven the girls out the house. They only come in to eat and then straight out again. I had cause to lock the cat flap this morning to prevent any leaving, only for a couple of hours, but I found the boys cornering one of my girls and she was very distressed. I am at a loss as what to do, at the moment I am thinking my only solution is to give the boys to my daughter, but I really love them all and don't want to lose any. Does anyone have any suggestions?
