I started pulling the cartilage in canine ears this year after seeing just how easy it come out.
Rather than pinning the floppy ears forward, I tried tucking a few of them inside like you do the front legs. I think it makes a cleaner look and lengthens the neck a bit.
There is probably no reason to do the Nevada stretch with our cats. Those Western cats have white spotted legs that can be used for pocket and cuff trim, so they like to show it off. Our cats are bland compared to western cats.
I would probably take the time to do it though because I like my fur to look perfectly groomed.
If I was doing cats that would be worth as much as western cats I might do it but I think the buyers are smart enough to not look at the legs much.I think they look just fine with the legs in.Heres mine from this year.
