Here are a few examples and ideas for what your character could look like. You can combine some of these.
Pelts:
The most common colors in the wild tend to be darker, like grays or browns, in order to make it easier to blend in with the environment.
Brown
Black
Gray
Orange
Yellow(ish)/Blonde
Russet red
White
Silver
Your characters fur can be long or short (in between as well, or long in some places with shorter fur in other places)
The cat you create can also have markings on their pelt, or a solid color.
Markings include:
Spots
Stripes (most common)
Splotches
Speckles
Socks
Your cat might be a "pointed" cat. Meaning it's face is a contrasting color from it's body, along with the ear tips, paws, and tail.
Your cat can be stocky and muscular, or sleek and lithe. Are they built for force or for speed?
Eyes:
Typical cat eyes are yellow-ish. They can be green, blue, orange, yellow, copper/brownish, or silver/grey. Normally cats who have blue eyes will have white in their pelt somewhere, and typically not much black, but we don't mind if you have a black cat with blue eyes. We are lenient with cats eye colors, as long you aren't too unrealistic. Keep in mind that your characters eyes can be mixed colors.
Ex: A muddy brown. Yellow-orange. Light green/yellow. Blueish green.
