All vets spay and neuter. I realize it might be different on ranches and that ferals become real predators. But the idea of a vet killing a cat? Don’t like it and she’s already been fired.
I understand your concern. There weren’t that many cats and we were never cruel or mistreated them. But they could be mean and the little kids had to be watched out for.
My Dad had a friend who was a Game Warden. He gave us orphaned fawns and a few baby raccoons. We took good care of them until they were able to get out on their own.
And we were “environmentalists” in our own ways. The stupid tree huggers don’t realize that people who rely on the land and nature for their livelihood don’t ruin that land or abuse nature.
