it depends what kind of cat it is
if your talking about female and male the males have a longer and pointier fin than the females.
Female cougars are typically larger than their male counterparts. Male cougars also of course have penis and testicles which may be seen between his hind legs. Females of course do not have these.
The male cats often avoid pregnant females unless one male is her dominant mate. Even then, however, he will do his best not to bother her because queens (pregnant/nursing cats) are very fierce and protective.
Male cats do not go into heat. Only the females do.
Male cats are somewhat more powerful than females.
I think all cats like catnip, regardless of gender.
No, to mate there needs to be a female and male involved
No, male cats do not have nipples, only females (girl cats)do this is when they are going to have babies, so the babies will be able to drink their milk.
Yes, un neutered males will try to mate with spayed females.
No, it is unlikely seeing as you are of two different species.
that males cant have babies and females can! lol i think
Usually no because the fixed females no long produce the hormone sent that attract males
