Pictures of cats: five sibling kittens

A top quality picture of five kittens smushed together keeping warm. They are a spectrum of coat pattens. This is how a litter of kittens turns out sometimes. They are tabbies. They looks incredibly healthy. All credit to the person who has looked after them in addition to the mom.

I would expect that these kittens have one father because they are similar. But sometimes the kittens in a litter may have different fathers. It is called superfecundation. I have written about this and if it interests you you can read the article by clicking here. I guess you might know that female cats can mate with different males when she's in heat. The release of her eggs are triggered during mating. Her reproductive tract contains the sperm of several males and chance dictates which male's sperm fertilises each of her eggs which have been shed from the ovaries. That's why you sometimes get a wide variety of appearances amongst siblings in a litter of kittens.
