Trixie and Pixie have been very moody today. They are usually a little moody with Manson but today they have been growling and hissing and fighting each other. It's strange they have gotten on pretty well since a week after I brought Pixie home but today its like they can't stand each other. Its not one being short tempered with the other they are both going at each other and both starting it, sometimes Pixie swipes first sometimes Trixie does. I know Trixie has been a little unsettled since George moved in but we are going very slowly with introductions and we are still on swapping scents and I hadn't been into George when I noticed the girls fighting. I just have no idea why they would suddenly dislike each other. Any one else got up one day to find their cats don't like each other?
