Jade and jagger litter
The silver kitten below will vary in color because silver is a gene that expresses itself in many ways. Sometimes silvers have some brownish tint to them called "Tarnish". The nice think about silver is it makes the background very light, which makes the markings pop out on the coat. Below is a picture of Bullet. Bullet is a full sibling to these kittens, although he was born about a year ago. Bullet is an example of a tarnished silver. While he looks like he is somewhere inbetween a brown and a silver, when standing next to a brown there is a big difference in his coat compared to a brown.
