We did away with our litter tray when our cat started going out earlier in the year as she no longer used it. She's usually a real outdoor lover, but now its winter, she's not keen to go out so much (and really not keen today with the snow and all). She's been out a couple of times just for a few minutes today. Im a bit worried she might start doing her business indoors again, and I obviously dont want to make her go out when we go out if the weather is terrible. Should I put her litter tray back out again? If I do, is there a chance she will over rely on it again come spring? What do other people do? We cant have a cat flap btw.
