We bought a brother and sister cat (same age) around 4 months ago. The female is in heat. Will she try to reproduce with her brother?

Answer 1

No, but he will
Get her Spayed, it is nicer to neuter

Answer 2

Of course she will, and the male will have sex with her, she will get pregnant and proberly have dead deformed kittens, get one of them to the vet to get neutered, then the other one, the male is a bit cheaper, but hurry.

Answer 3

ABSOLUTELY!!! Separate them. Kittens can reach sexual maturity as young as four months so if you haven't she could already be pregnant. WTF? Why haven't you altered them? I'm betting you also haven't bothered to get them any of their shots, have you?

You BOUGHT kittens? From where? Reputable breeders tend to alter kittens before they are sold. So you bought no breed kittens????

Answer 4

YES. And if she gets pregnant at her age, she is likely to have very serious complications including death giving birth. She is likely to kill or ignore baby kittens as she is a kitten herself.

Separate them NOW. Get an emergency spay done by end of June and get him neutered too. Most vets will give you a little discount if you do them together instead of one now and one later.

Answer 5

Absolutely. Probably she already has. This is their first time, so it might take them a few minutes to figure out how to do it. But not much longer.

Answer 6

Yes. Get them both in to your Vet for a spay and neuter ASAP. If you have to ask a question like that only shows that you know nothing about cats. they will reproduce and being so close in bloodline will only produce kittens that could be deformed and sickley. Get them in. Good Luck!

Answer 7

Yes, they have no concept of inbreeding.

Answer 8

Yes. At 4-6 months, or whenever they sexually mature, all kinship goes out the window and they are total strangers to each other and they WILL reproduce; there is no "try" or "might," they WILL, if neither of them are fixed. Get one fixed now if you're low on cash, at the very least, preferably the female.

Answer 9

of course she will, and if she's in heat now, probably already has. Very irresponsible not to have spayed and neutered by now

Answer 10

No, please don't. There are far to many unwanted cats in this world as it is. Keep them separated, you can get her spayed as early as six months old.
