I'm looking to get one for my Cats. I will be leaving them for almost 2 weeks with a pet sitter popping in to check on them I'm finding myself wanting to 'abandon proof' them because I have this fear that the pet sitter won't show up. Which is completely ridiculous since I also have one of my friends popping in to check them. Anyway this may be a silly question but are all cat water fountains electric ie need to be plugged into the mains? Because I don't want to leave any electrical items on while we are away. Possibly another irrational fear but I don't want to leave any chance of an electrical fire. Heck I won't even let my OH charge his toothbrush while we are out at work since I got the Cat's! And please tell me that I'm not the only one who feels a bit sick at the prospect of going on holiday and leaving their pets behind? My OH thinks I'm being ridiculous because "they are only Cats", but I worry that they will get lonely and think I have abandoned them.
