Marty Moose has been hiding a lot lately and not been very active. We figured it was from the heat and didn't think too much of it. I was petting him last night and found huge, huge lumps on all of his lymph nodes in his neck and head. A few in his belly too. These weren't there last week when I brushed him. Last night we also noticed some labored breathing. :( Headed to the vet this morning, but I don't have a good feeling about what's going on. He's never been a healthy looking/acting cat, despite only being 2 years old. Plus he's lost a fair amount of weight in the last few weeks (hard to notice because he is so long haired, and he's been unwilling to be picked up lately).
