This is interesting to me because I have both a spayed dog with a tattoo and a cat with the top of his ear cut off. We adopted our lab mix from a rescue who told us what vet we had to use to get her spayed. We weren't told beforehand that she would be tattooed but afterwards were told that the rescue insists on it.
Four years ago we found a cat on Christmas Eve hanging out around our house and it was 17 degrees! When we took him for a vet visit I asked the vet what she thought happened to his ear and she told us about the feral cat thing. The strange thing with him, though, is that from the first night we found him he's been the friendliest, most lovable boy and tolerates all of Puff's pouncings and shenanigans with no problem.
