I have two cats, one hardly goes outside and one is constantly coming and going. I’d really love for her at least, to stop using the litter tray....the strange thing with her is, she has a preferred spot in my flower beds where she goes for her morning poo without fail, even in the pouring rain. However when it comes to peeing she insists on doing that in the litter tray. Is there any way of getting her to do all of her business outside? My other cat has shown zero interest in moving from the litter tray to outside so I’d be reluctant to move the tray outside altogether. Any help or advice greatly appreciated!
