Ace;
I can't really answer your question. Sometimes I get good clear bellied cats with no spots on their backs and sometimes clear belly with great spots (almost like ocelot). Then there are the plain old "rabbit backs"we often get here.
There also seems to be a vast difference in sows that have had kittens. Most of the time here, they will not be nearly as good as toms or young cats that have not had kittens. Often they will be very short on the back with few or no spots up high and the bellies will be rather tinged and not clear at all. However, this cat was a sow!
Down in west Texas, they have a extremely sought after spotted cat. A big broker from New York called me the other day wanting to know if I had any of that type cat. Since I am no longer buying, I didn't have but a couple. Of course, those big blue cats found in the west & northwest are the ones that will really bring in the $$$.
Every see a black bobcat. There was one called in with varmit call here a couple of days ago. It is at the taxidermist to be mounted.
