A female human does not get "fixed" they have what is known as a hysterectomy or the removal of the uterus. In this case no, but this operation is done only in extreme necessity.
No, when a female is spayed all of her reproductive organs are removed. She can no longer come into heat and bleed.
No, a fixed male cat cannot impregnate a female cat because neutering removes their ability to reproduce.
it shouldn't, get to a vet
He still has the hormones and instinct to do so, but not the physical ability... do not be alarmed by this, even if the female is not spayed, nothing will happen.
Even if a female dog is fixed, if she is on her period, there won't be blood, but she will still give off the nasty smell and that could possibly attract the males, yes. Sometimes though, a male dog (or MAYBE, female) just gets overexcited and, well, you know the rest :D
Yes , its not as easy but still possible as long as the female is still getting her period.
Yes but if the operation on the male was successful the not by him
Yes. Some birth control forms can stop a female from bleeding but she still goes through the rest of her period.
She will no longer have a period because when she gets spayed all the vet is doing is taking out her reproductive organs
Sometimes a fixed female cat will still have the instinct to urine mark her territory. It can also be a sign of a urinary tract problem or infection. It is best to seek veterinary advice if your cat is marking.
No, after being spayed, fixed adult female dogs no longer go into heat because the surgery removes their reproductive organs, including the ovaries which produce hormones responsible for the heat cycle.
They still may have the urge after being fixed if the female is in heat, or goes into heat. Just because the male is fixed, doesn't mean he has lost the urge, or can't do it any more. All that has been removed is his nuts and sperm. Therefore, the male and female can still mate and get locked up, but can not get pregnant unless it is recently after the male has been fixed and he still has a little bit of sperm in his system.
