Hello, I have had Sphynx for some time now but earlier this year I got a new breeding male. He was a yr old import from Russia and a proven Father. Off the bat he seemed to do okay with out females but got very hateful and aggressive so he had to go to his own room. When I have a female that I wish to breed with him even if I’m the posing position he attacks them and tries to hurt them the best he can. I have not had or heard of this happening with other males. So my question is could it be because he doesn’t have any other cats with him? Or should I just neuter him and how to find a younger male to raise around my female? He has an extensive pedigree. But I want what’s best for both him and my females.
