At what age do cats stop having kittens?
Pretty much their whole life. But I suggest that they be spayed around about 5 to 6yrs old. But remember that at 5 to 6 yrs old you're looking st a CATS age at 35 to 42 yrs old. They can have kittens way after that. But remember the toll and physical drain it puts on them. They have nurse the litter also. There will be people who will argue with me about it. That's fine. It's their belief if that's what they choose. I've went to 6yrs of age. But stoppped after she raised her last litter. If you're not going to breed her at all, I suggest that you get her spayed before she comes into heat. That will lower their chances of breast cancer and other types of cancer. I've had that done with my females. With a low rate of cancer risk. Nothing is 100 percent. But lower the odds the most you can.
At what age should cats mate?
Generally Cat Fancies (societies for cat breeders) state that a queen should be at least 12 months old before she has her first litter of kittens. This means she should not be bred before 10 months of age. Many queens will be cycling before that and it may be necessary to control their cycling by controlling the hours of daylight they are exposed to, in order to stop them cycling. Alternatively hormonal treatments are used by some breeders, although the lecturers at the veterinary school I went to were opposed to the use of drugs to control the cycles of breeding cats, or dogs either for that matter. If a queen repeatedly cycles without getting pregnant, she is at significant risk of pyometra, which is a form of infection of the uterus. The uterus fills with bacteria and pus. The bacteria produce toxins which impair kidney function and the queen is very likely to die of kidney failure and dehydration. Alternatively she may die of sepsis. As a cat breeder who trained as a veterinarian and veterinary pathologist, before quitting the veterinary field and retraining as a toxicologist, I use control of daylight hours to prevent my queens cycling when it is not appropriate to breed them.
Will kittens/cats mate with family?
yes they will. be responcible and get your animals fixed and stop contributing to overpopulation and the murder of so called unwanted animals
If cats from the same litter mate, will the kittens be deformed?
So I have two kittens from the same litter. The female has gone into heat at 4 months old (way sooner than I expected) so no vets will spay her for 3 weeks when she is out of heat. I am trying to keep the male and female separated, but what if they end up mating? What are the chances that the kittens will be deformed? Also, the female is only 4 months, how will that affect her?
If two cats from the same litter mate, will the kittens be deformed?
It's likely (but not absolutely certain) that the kittens will be less healthy than normal. One thing about cats is that a female can mate with more than one male during one heat, and the kittens in the same litter can have different fathers. It's possible that they aren't full brother and sister (but that will only make a relatively small difference in the likelihood of their being less healthy).
Best age to get kitten spade or nudered?
Sooner is not better I don't know who said that. You are supposed to wait until the cat reaches "puberty" par se... so generally it is best to be done around 6 months. However they can be fixed as early as 3 months but this may effect the behavior of that cat later in life, because when you have a cat fixed that early it is as if you are completely "unsexing" them. But if need be you can have the fixed at 3-4 months without much detriment.
If a male cat gets his sister pregnant will the kittens be deformed?
No, they won't be deformed. It takes a many generations of in breeding to create deformities. In fact, when trying to breed a particular colour, they usually cross-breed cats that are closely related. As it is your cat's first litter, and she must be quite young, she will probably only have two or three. Start looking for good homes for them before they are born, but do not take them away from their mum until they are at least 7 or 8 weeks old. Take the boy to the vet and have him neutered, while the other is still pregnant. Then get her done when the kittens are about 5 to 6 weeks old. By then they don't need much milk from her. But they should stay with her for a few more weeks, to learn proper cat behaviour (eg using a litter tray, grooming etc).
