what would happend if you mix a siamese with a calico

Depends what color the siamese dad is. It’s the male gene that carries the color, and a calico female doesn’t produce calico babies. To get a calico you have to have a red (orange) dad with a black mom.

its a silico

It will be like an unknown mixed breed

Insanely cute!!! Hmm, it would be a neat experiment to see what the kittens would look like.

Actually, we have a calico siamese mix named Demi. We raised her from 6 weeks old to her present age of 9 years. She has a lot of siamese traits in both temperment and appearance and has always been a handful. She is very high-strung, dependent and an biter. On the other hand, she is strikingly beautiful and very affectionate, but on her own terms. I would recommend that you already be an experienced cat owner before adopting one. Otherwise, be prepared for a few bumps in the road. (I attempted to post her photo to my profile but have been unsuccessful so far.)

I have added Demi’s photo. Notice her profile is very siamese but her eye color is green, not blue. Green eyes are typical for a calico. Also, she is not verbal like most siamese. When she wants attention, she will head butt or jump in your lap.
