I'm now sure that The Smalls has colitis caused by leukemia. The last time the vet did the big leukemia test, he still showed signs. She said to come back and retest in 2 months. That's tomorrow. He thew up once on Friday, once on Saturday and once this morning (so far). And diarrhea and straining to poop and mucus. Google is pretty clear about the cause. He seems perky, but I am worried.
So tomorrow morning, it's off to the vets for him.
I knew this was a possibility before I even met him. It's what I took on. And he's not dead yet. And the vet may have entirely different news. But, still. I'm sad.
