Hello lovely cat people..I’m desperatly looking for advice. I have two indoor, 5 year old rescue cats, my wee girl is a perfect normal cat, my boy has has a lot of problems since I adopted them last May. He started weeing outside the box which (long story short) he ended up diagnosed with struvite crystals. He’s better now hes on a prescription diet, and doing a lot better (apart from still needing to lose 1kg) ..he’s never been 100% with using the litter tray after that but was doing well, until recently where he has really stopped using it pretty much at all (he still poops in it but wees on the floor!) and I am at my wits end...I really have tried everything and even the vet seems to have run out of ideas! If anyone can offer advice I’d be eternally grateful!! xx
