Our v-e-t came last night. Mo and Spud were due for check ups and vaccines. They are doing well though Mo did try to bite the tech (oh my).
As for Maestro, they took some samples from the lump. He is kind of stiff as well but things are limited for cats. We should hear something back by the end of the week. The doctor thinks it involves his salivary gland....either an infection or a tumor. Mom talked to the vet about how much to do and while mom can medicate him she is reluctant to go to extremes due to his age. We will keep you all posted.
