I have an 8 year old cat who has almost always used a litter tray inside
(for a few years whe went out the window and in summer tended to use
outside). I moved to a new flat last year and recently put in a cat
flap, but although she goes out and in frequently she still uses her
tray inside all the time. I tried putting the tray outside ,she used it
but didn't click to start using the soil. It then rained and the tray
got covered in slugs (yeuch!) so I had to abandon that idea. Has anybody
any ideas as to how to persuade her to use the soil outside?
