Well, he had his vet appointment today. I found the whole thing rather upsetting. The vet isn't sure right now how to diagnose him but to me it seems like its leaning to the side of the worst possibilities. All his glands (in his neck and apparently near his hind quarters) are swollen and he has the large lump on his neck near the shoulder. The vet was saying that he seems to be showing many of the signs for a type of lukemia except for his behavior. Peachey is behaving normally, eating well, and not losing any weight, in fact he gained a little bit in the past month and a half. They have taken some tests, I forget what it was called but its when they stick needles in and take some samples. The vet also ordered the tumor that was removed a month and a half ago retested as she can't figure out why that would have come back as not being serious and then this lump reoccuring so quickly. The vet is going to run the test and they are sending the samples to a lab so they can also run the tests. They are calling me with results tomorrow, but I'm not sure if those are their results or the lab's results.
