Xenon hospitalized

Xenon took a turn for the worse this weekend. I brought him to the vet this morning and after checking his levels, his kidneys are failing.

My 11 year old cat is just not acting himself lately. He's not his happy go lucky, pushy for attention self. I took him to the vet and the bloodwork came back OK and they can't find anything wrong, just that he was a little dehydrated. I don't see any evidence that he got into anything either. Nevertheless, I am VERY worried about him. He's resting today and hopefully will be back to normal soon.
