No, a fixed male cat cannot impregnate a female cat because neutering removes their ability to reproduce.
by mounting it
Yes; for about two weeks after neutering a male can still impregnate a female.
the dog can impregnate a female in less than 5 months of it life
Yes. Only the testicles on the male have been removed, not the penis. Penetration will still happen, as the male dog can still maintain an erection. There is just no sperm production. Indeed, neutered male dogs can maintain an erection, penetrate a female and actually achieve orgasm, and will "tie" with the female. Most neutered males are less interested in sex due to lowered testosterone levels, but still capable of all the actions. They simply do not produce sperm and cannot impregnate a female.
Yes but if the operation on the male was successful the not by him
If your female cat is fixed aund another male cat is not fixed your female cat should not be attracted to the male cat but the male cat could be attracted to your female cat. ;)
Simple- he can't.
Only a person that was born male, and still has their natural penis and testicles can make a woman pregnant. If you were born biologically female, and surgically altered to male, then you cannot impregnate a woman.
A transsexual woman, who is a woman born into a male body, can impregnate a girl if she still possesses her male genitalia, and has not been rendered infertile by estrogen and anti-androgens. Since transsexual men are born with female genitalia, they cannot impregnate women.
yes, they can have threesomes
Strictly from a population standpoint it still makes a difference. Most cats maintain a territory, they can overlap but they will defend the area they live in. If a male is defending a territory and is unfixed he will try to impregnate every available female. If he is fixed he will still run off other males but be unable to mate.
Not unless some form of artificial insemination is being used to impregnate them. Female guinea pigs cannot self-impregnate.
