My cousin and I, years ago, both work at a vets office, two different vets. Plus I used to work be a dog groomer and a dog and cat boarding facility manager. Between the two of us, we saw lots of cats. One actually was a male calico, a client of the vet my cousin worked for. Never saw or heard of one since.
A lot of people don't know they are always female except for that very, very rare occasion. If we would have thought of it, we could have made lots of money betting people on the sex of the calico lol
