We have two kittens (brother and sister) that are 15 weeks old. We're going away for 48 hours (Friday afternoon - Sunday afternoon) and we've asked our friends if they can come over on the Saturday afternoon to top up the kitten's food, change their water, empty the litter tray, and give them some attention (play or cuddles depending on their mood!) But will this be enough? I'm worried about the kittens being by themselves for 2 x 24 hours. Should we take them to a cattery instead?
