Yes. A can will accept a mate and become pregnant only when she is in heat. At no other time will she want to mate.
Yes. In fact, that is the only time that a cat can get pregnant.
Male cats won't fight over a pregnant female. In fact, they couldn't care less about her if she was pregnant. But they will fight over a cat that is in heat.
Yes, I've have had a cat that purred while she was pregnant.
She will show signs of heat by rolling on the floor and tempting the tom. A pregnant cat will not show any of these signs.
You can't. A cat will stay in heat and continue to come into heat unless a male cat mates with her, or she is spayed. Unlike most mammals, cats will only ovulate while in the act of mating, so nothing else (unless spayed) will actually stop the heat cycle.
They get in heat and a male cat impregnates her.
No, when a mammal is pregnant it will not go into heat while it is pregnant.
Cats are notorius for having false pregnacies.
No it does not. Basically the female cat will stay in heat until she is bred and pregnant. That is why you need to spay her as soon as possible. Other animals such as the dog have a set length of time for their heat cycle such as 2-3 weeks and then they are out of heat but a cat when she comes into heat, stays in heat until she is pregnant. Spay her! Good luck.
Yes, any other time she can not get pregnant. I have never before heard of dogs getting pregnant while they were not in heat.
No; Only when in heat is a female cat interested in a Tom cat.
Yes. A cat can have kittens from different fathers in the same litter.
