Hi, we adopted a cat a few years ago. She was a stray kitten and we took her on after nobody claimed her following posters etc. She wasn't chipped. We've had her neutered. All well and then a couple of years ago she stopped toileting outside so we have a litter tray. Not great but could put up with that. Now she has stopped using her litter tray and craps all over the bathroom floor. Have tried everything - changing tray more regularly etc but there is a limit as we both work full time long hours. If we give her up what can we do? Do we have to have her put down or will an animal shelter take her on? Thanks in advance.
