I've had a cat before that died from kidney failure and it was heartbreaking at the end. As much as it will hurt to let him go I have promised him that I will not put him through that. Re-reading the stuff on kidney problems it does seem he is showing more signs of low potassium.
This morning he has been round to say hello but only after he saw me at the door to the shed. He's eaten less than a teaspoon ful of food.
The vet on Saturday said he was just showing signs of a temperature and everything else was fine.
I know in other cats that I've had that have been dehydrated they have had a water injection and then all started eating again so I may ask if he can try that - I do want to give him every possible chance but on the other hand he has no quality of life at the moment. The last thing I want him to do is die in pain somewhere.
I hate making this decision.
Edit - booked in for 10.30am. He has no quality of life so unless the vets can offer some sort of miracle to get him eating then I think I will have to say goodbye. I can't put him through waiting for blood test results, it's not fair on him when he has no quality of life. He's sat next to me purring - I've hardly ever heard him purr and can't think it is a good sign. I do think the kindest option is to let him go.
