I have figured out he is constipated.

He's in and out of the litter box this morning, but not like before. In order to help him stay on his diet I have switched to dry food as it's easier to measure. As a result he is drinking a lot more water!

(Last time this happened I paid $350 at an emergency vet to find out two weeks later that he had no bladder infection at all.)

I put some Laxatone on his paw and hope that will help. He's just got to wait.

On the good side it's looking like he will need an insulin injection only once a day, and perhaps a lower dose. Also, his last "buffy coat" test at the oncologist showed no mast cells in his blood at all.

Sigh. I love my baby.
