It probably sounds ridiculous but I've not been away for years because I'm worried about leaving my two cats, but I now have two human babies and want to go away next summer. I've heard horror stories about catteries so would rather have a cat sitter but I'm worried they will fight when no one is with them for long periods as they do scrap sometimes. How can I make sure they are as comfortable as possible whilst we are gone? Maybe I'm overthinking.
