My cat is 14 and has just been diagnosed with kidney disease. He's also recently started not going out so we have a litter tray for him which he uses. A couple of weeks ago we discovered a large puddle on the kitchen worksurface. We assumed this was sick as he drinks so much water. He's done it repeatedly over the last few weeks and today DH caught him in the act and discovered that he is actually weeing on the worksurface.
What can I do to stop it?
