I have kept off the forum for about a week as I thought it would be best. I have taken the comments on board and would like to say I would never intentionally upset my cats or make them miserable. I do now leave them together and they have the run of most of the house (apart from the kitchen, bathroom and my daughter's bedroom) and have had no problems at all. I don't have the biggest house but there is plenty of room for the cats to get away from each other if they so wish. I attach a photo of the 3 of them sitting on the windowsill plus a few other photos. Betsy loves chasing Eric up and down the stairs and Kizzy has washed her a few times although Betsy is not too sure about this!
