I have been trying for 3 weeks to get another urine sample out of Tom - he peed up the wall one day last week, and peed in the kitchen yesterday, so the rescue have spoken to her vet and they have decided they will keep him in until they can get a sample. She was also concerned about diabetes as he drinks a lot and is overweight, but I said my vet thought he may have kidney issues, and her vet told her the same, so they may also be running blood tests on him. I have also asked them to look at his teeth, although I hope that they dont do a dental, as my vet thinks he is too overweight to withstand it, and although he has lost weight, he is only down to 8.6kg. I was happy with him being there for the day, but wasn't happy when she said 'In case he is there for a couple of days, can you let me have some of his special food in case she gave us everything she ordered'. I know it is good he will be there till they have either declared him healthy or found something, but I don't know what will happen if he does have an illness - he is already going to be hard to home due to being 12, and we will have to make sure whoever takes him is willing to work with him to keep his weight off.
