Sorry, I haven't written, things have been real hectic (personal stuff). When I picked up Mittens, I've never been so comfortable! He went into detail with everything and told me what our next steps would be if the medicine and new food didn't work. It was truly perfect! He even carried Mittens out to the car after it was all over!! I haven't been at home for more than an hour since I brought him home because of my crazy work schedule at the museum, but my mom called and said he is using his box and when he goes, he is peeing a lot at one time. He loves his food, and she believes it is working! She said she hasn't seen him so frisky in months! Looks like this is the answer--let's just hope!
The urine culture comes back tomorrow and we'll know more. Thanks everyone!
