None of mine came with papers and most of them were what is called DSH or DLH; Domestic Short Hair or Domestic Long Hair. Aka; Mutt. My first guy was a beautifully shaped black shorthair from the shelter. When he needed a playmate, a stray had showed up at a friend's and I took her to live with me. She was probably the ugliest shorthair I'd ever seen; very out of proportion. Then one day I looked at her and realized that she wasn't an ugly shorthair, she was a Siamese with the wrong paintjob. She had a very Oriental build and voice, and a little bit of the Oriental personality. Later, when I was doing TNR, the first cat I trapped looked exactly like an Oriental Shorthair (a breed that looks like a Siamese but without the colorpoints). This girl had grey tabby coloring, but everything else was pure Oriental! They can be very possessive of their people, and this girl didn't want to share me with my other cats. I found her another home where she settled in as Queen of the House. One of my current cats strongly resembles a Maine Coon. They are known for being very large and very mellow. Main Coons are known as the Gentle Giants. Magic qualifies on both counts. He also has the strong squared muzzle and huge feet common to the breed. I also took in a pregnant teenage foster. She was all black and at first I thought she might be part Siamese. She gave birth to two black and white fluff-balls. She was apparently carrying the recessive longhair gene. When she started getting enough food, she filled out a bit and I realized she more closely resembled the slightly stocky build of a Persian, and though she was a short hair it grew in soft and plush. Her daughters grew Persian-like coats and had round heads with slightly shortened muzzles like an old fashioned Persian. There was obviously some Persian on both sides of that family tree!
