I know this must feel so stressful. You see all the pics of the kitties at PT that get along so well that you might feel like something is wrong with your kitties.

This is not the case. They will adjust. They might become snuggle kitties but they might not. My kitties don't snuggle or groom or any of those other cute things that some people's kitties do, but they know that they are family.

Take care - it will get better.
