Our usual mix is two males and a female. We would agree, the boys are definitely more affectionate and sociable. Before we became addicted to Abyssinians, we'd have two boys. At that time, cats just showed up and claimed us, and not surprisingly, they were toms (when they arrived, we took care of that in short order.) When we finally were contacted about an aby litter, we were entranced by an exquisite little princess. She promptly cowed the two resident alley cats, and she was fairly affectionate. THe girls (at least aby girls) do like to play and Wynki will indulge in a game of chase and be chased with the boys, otherwise she has nothing to do with them, no snuggling or grooming. We find the two to one arrangement delightful.
