Pretty much. You'll see those striking pattern differences as one good indication. It is important to note that even humans can be chimeras - although they usually have diffuse populations of each embryo's descendant cells, as for it to work in humans, it apparently has to happen extremely early in development, like possibly as low as being 1-8 cells each.

Worst furry convention ever.

At least her head isn't orange, so perhaps she has some braincells that aren't shared.

Did she swim in Mac&Cheese?!

Does she get less of the brain cell or does she get some of her own?

I have a shorthair muddled calico. She’s got one grey leg and one orange leg. Super cute

Similar in that they are both cats?

I wonder if the paws are influenced by the quantum braincell.

One of those "box of spare parts" cats.

This is clearly a chimera, admittedly not the most exciting chimera considering the options.

If you enjoyed my comment please enjoy this image I stole from another post. If you didn't enjoy my comment please do not look at this meme.

Serious question: is this because she's a calico?
Euchre
That's not a calico, that cat is about certainly a chimera - two embryos fused very early in development.
zyuna
Very interesting! Thank you.

Is chimeraism easier to spot in cats because of the various pattern cats have even within one litter?
