I think many hobbyists refrain from breeding crosses for both ethical reasons and practical reasons. Unlike dogs , there is no pedigree registration available to insure pure bloodlines. Also the issue of , who will buy the chams , arises. You probably will have no problem selling the males as pets , but you may have a problem selling the females. The industry is already filled with misrepresented Panthers , as some unscrupulous breeders misrepresent their offspring , just to sell them.
Here in Canada , there has been such a wide practice of mutts for sale , for so many years , purported to be pure , that I can't reliably acquire new bloodlines to add into my projects , without having to investigate the source. I am even aware of misrepresented mutts being sold into the Canadian market , from foreign sources also.
