If one kitten is black and the opposite is ginger, however the mom is a Siamese cat, how might they’ve obtained their appears via genetics? Should you’ve ever puzzled about this, I’ve the reply for you!
Nicely, the mom isn’t the one genetic contributor, and feminine cats can mate with a number of tomcats earlier than their eggs are launched and fertilized, leading to totally different fathers and totally different genetic contributors. So the brief (and interesting!) reply is that sure, a feminine cat’s litter can come from totally different male cats! Let’s be taught extra about this:
What’s Superfecundation and How Does It Work?
Superfecundation is when greater than two ova are fertilized by totally different males throughout the identical warmth cycle of a cat or different animal, which ends up in conception.
An unspayed cat goes into warmth each two to 3 weeks and is fertile between 1 to 10 days.

Simply as clear because the indicators will probably be for you when your cat has gone into warmth, they’ll be for tomcats as your queen will launch pheromones off their physique and of their urine that instinctively communicates that she’s able to mate.
When a free-roaming unspayed feminine cat is able to mate, she is going to – and with a number of male cats. Nonetheless, cats solely ovulate round 20 to 50 hours after they’ve mated. By this time, a feminine cat will have already got the sperm wanted for fertilization of their reproductive tract, and if she mates with a number of males, they are going to all have an opportunity at fertilizing a number of eggs.

If a queen mates once more, and totally different sperm fertilizes one other egg throughout her fertile window, that egg can even observe the pure path into the uterus. The extra a cat mates, the extra eggs that will probably be launched.
These totally different fertilized and implanted eggs will develop on the identical time over the subsequent 65 days or so – despite the fact that they’re separate litters. Though from separate litters and separate fathers, they’ll be born collectively on the identical time.
Though not quite common, it’s potential for there to be as many alternative fathers as there are kittens when the mom cat offers start.
How Can I Know If Superfecundation Has Occurred?
As I’ve talked about, if kittens from the identical litter have totally different personalities, coat colours, eye colours, and hair lengths, they in all probability have totally different fathers.
