I have to go away at the last minute and will be gone for 2 days. I'm wondering if I can leave my cats alone for 2 days with plenty of food and water but also, should I leave the cat flap open? I usually don't allow them out at night because the neighbours cat is out at night and they have got into fights in the past (my cats are smaller than the neighbours cat). My cat flap does not have an auto lock and I don't have anyone to come and let them in an out. I'm wondering if it is better to risk it and leave the cat flap open for the 2 days or keep them in the whole time? Yes, I'm a sad cat lady and I care far too much about my cats!!!!
