The American Shorthair fishbone pattern is a string of strings. It is a hybrid and looks like a civet cat. This kind of cat has a higher probability of developing diseases. When breeding cats, it is best to choose cats of the same species of the opposite sex for mating. In this way, the cat's life span will be longer, and the appearance of purebred cats is relatively good, and there will not be much difference. During the breeding period, the cat should be dewormed on time and the cat's nutritional supplement should be strengthened.
