Cats’ coat patterns appear first on their head and tail and then on their back and belly.

After the patterns develop on the cats’ head, tail, and back, they may end up having a patternless, white belly if they don’t have enough pigment cells.

That’s why there may be cats with a dark back and a white belly but not those with a white back and dark belly. It is also why cats have white feet.

Some say that cats with white fur and blue eyes have hearing disability.

While the probability of hearing disability is higher for cats with such fur-eye color combination, it is not always the case.

Also, if a cat with one blue eye has hearing loss, they have difficulty hearing with the ear on the same side of the blue eye.

If a tabby cat does not have an M-shaped pattern, it could be that the color of the fur tips is different from the roots.
In such cases, the M-shaped pattern won’t be so visible due to the fur color.

There is a 1/3000 probability that a male calico cat will be born. If so, it will be because he has an XXY chromosome combination.
