Occasionally, cats with v-cuts come to our clinic and we certainly wouldn't put them under to alter their ear again. It may be stressful to be re-captured and transferred to a clinic but this isn't an issue only for cat's with straight cuts. It's also good chance to give them any treatment they may need. Our opinion is that both v-cuts and straight cuts are both acceptable methods for identifying cats that have been spayed/neutered. We aren't asking or expecting anyone else to change the way they prefer to do things and we ask for the same respect.
