Merlin was very sick today, and my regular vet was closing in half an hour. Because we are still limping along after the dramas, we rushed into the other local vet.
Merlin walked through laundry powder that had spilled. This made him very sick when he cleaned it off his paws afterwards.
BUT it was only temporary - AND it gave us the excuse/opportunity to run new blood tests... As suspected, Merlin's kidney failure was an acute reaction to dehydration during his recovery from surgery. On his new diet, and after all the special patient loving care, Merlin is now wonderfully happy and OFF the organ failure list. He is WELL!
