My 2 cents in show picking. While its great for the breeder to pick out show quality (and should be that way), IMO you should know your breed standard well enough to also give your input as to what you like in the kitten (per standard) and give/take between you and the breeder in picking out the best kitten and why.
I kinda feel that when a person asks for show quality, they should KNOW the standard well enough to critque the kittens too - and know enough to explain to others why this kitten is show quality, best features...in other words "what makes this kitten show quality over another".
I know a lot of people are not skilled to evaluate, but you can do a decent job by studying. After we got Charlie, I studied the standard and evaluated the cat (good and bad points) and learned what to look for in type, head, spotting, etc. So when I put in for another "show" quality Oci, I know what I needed that was better then Charlie had. I could help evaluate the litter and pick out a show male (Jack). Between me, the breeder and another Oci breeder, we narrowed it down from the beginning to 2 males. In the end we all agreed that Jack had the better overall qualities in a show cat (even if his brother's ears were what I would have wanted on Jack; Jack had more going for him in other qualities).
Mews - you have one Sphynx - and by now you should know the standard that you can evaluate the kittens as well and not rely totally on the breeder's pick. What qualities in the ones you are picking from would you say is the show quality one and why? Keep in mind that breeders can sometimes become "cattery blind" where they think their cats are all great. Its better to get one or two other opinions from trusted breeders to help clarify which one you pick.
Anne had no problem with me sharing the pics of Jack and by phone or emails we gave our opinions. I wanted to learn WHY they chose what they did. Even if I don't breed, I can tell what makes a show quality Oci (and other breeds).
