We moved yesterday and as it is about 2mins from the old house I fed the cat there and left him out. He is an outdoor cat since we had the dc (poor thing!) Anyway we are going to feed and collect him this am. Is it absolutely essential to keep him inside? I don't have a litter tray as he is outdoorsy so I would need to get one. If I let him in the garden to use the loo would he run away? I know he will hate being kept in, might not use the litter tray and pee in the house, and will probably escape as we/kids go in and out. But if I let him out I'm worried he'll get onto the main road. Also, how many collars?! He loses them every few weeks, surely not normal?
