He'll be fine. But judging from the last time he was left at the vets for the day, he'll revert to the feral he would've been. I feel sorry for the vet techs.
Floppy has a lump on his neck going on 1 month now. I took him to the vet and it was diagnosed as a harmless cyst. The vet said that it could be left alone. But, his teeth are finally in need of a cleaning, after years of being borderline, so I reluctantly agreed to schedule the procedure, and the cyst will be removed at the same time. I hate the fact that he has to bear the experience of being in the hospital alone.
