I brought in a urine sample for a re-check on Scruff. The vet called and said Scruff's crystals are gone. He still has a high white blood cell (I didn't know they can check that with urine), so they are refilling his Primor. They beleive he has some kind of infection still going on. I updated them on his diet. They said that feeding him a Raw Diet is great. Especially adidng in the Missing Link Vitamin Supplements. I am so glad he is getting better. I just hope this infection gets cleared up soon!! Thanks everybody for your help and advice.
