The vet wants a urine sample from our (probably) 16 year old cat as he is possibly diabetic.
I have the equipment but he has never used a litter tray and I have been unsuccessful so far. My attempts to drag his paws through the non absorbent litter whilst making running water noises have been met with bemusement. I left it by the door as I had go to to work and later found him sleeping it!
Any tips as otherwise he will need to spend a day a vets trying to extract the urine from him somehow. I don't want to think about it but I believe there are various methods. I think this will be stressful for him and expensive for me.
