I have a couple of questions about breeding cats. could someone please help me?

Question

i have these two kittens whom someone left in a box on my door steps. I got them in may n the vet said they were about 7 weeks old. I am pretty sure they are brother and sister too. but last night i heard my girl cat crying so i went in their room n the boy was trying to mate her while biting her neck. so i have a couple questions.

if the girl cat has kittens will they be normal or deformed like a human baby would be in this situation?

how old are cats when they start mating? these are still kittens not even 6 months old.

what are the first signs if my girl cat gets pregnant? how will i know?

please could someone answer those for me. and before you go on and on about how i should have gotten them fix. I was getting around to it. like i have a vet appointment and everything for them next week.

Answer 1

they could get pregnant,just continue with the vet appointment and keep them separated till then,the kitties born could be deformed and she could die from being too young,just quickly get them fixed like you planned,thats the best step.

Answer 2

If you have an appointment for them next week then what is the point of this question.? If you get them fixed within the next couple of weeks there will be no problem. They are of the right age to be fixed since they will soon be old enough to mate.

*******This is the second time you have asked the question about whether two cats that are related would have deformed kittens. If you are going to get your cats fixed then why are you asking this question again?

Answer 3

You will want to get them fixed as soon as you can. Females can get pregnant as early as  4 months and you don't want that.  

Yes, they would have incest kittens and they could be deformed.

Answer 4

yes, they can look deformed. its bad to breed them within their family. but she wont be prego anyway. if they are that young, there is no way either one of them is fertile, unless they are over 4 months of age. the reason why you saw them doing that was what kittens and puppies to to each other to show dominance. when they do that at such an early age, it's just to show the other that they are the alpha. not a big posibility of being pregnant. unless, as said before, over four months of age

Answer 5

she wont get pregnant shes too young. bottom line.
