@JBTO: it was explained to me by wiser and more experienced souls that male cats are more likely to be dumped because they spray nasty smelling urine when they are looking for female company. And I think male cats are more ornery when they are looking for female company and cant' find any; female cats in heat are VERY affectionate. (There is female cat in heat at the cat sanctuary where I volunteer who is very affectionate right now. Because her health is compromised (FELK+), the sanctuary is reluctant to spade her. All the other FELK+ males have been neutered.)
