So, we moved house 5 months ago now and our two cats who are 9 had never really used a litter tray other than when they were kittens, but as we needed to keep them in for a week we had to get one. But it seems as though they have got used to it or just being lazy as they refuse to go to the toilet outside. We've tried it all and when we took the tray away completely they both pooed indoors on the floor which mortified me slightly so the tray is now back, and I am at my wits end emptying it about 4 times a day, any advice please? Surely they're not too old to be going outside now. The garden is a lot bigger and their are a lot of other cats about, but we've found them a great little spot near the catflap and put their litter and poos and wees in it etc... But it's not happening, so really in need of advice as I can't have them pooing on the floor as I have an inquisitive three year old that I do not want going anywhere near it obviously. Thanks.
