Shedding, molting, whatever

Technically, it’s called molting, but owners usually just speak of shedding, and it’s one of the less pleasant aspects of cat ownership. Cats living in the wild molt hair in the spring, leaving them with a shorter (and cooler) coat for the summer.

But most house cats live in an environment that is artificially lit, heated, and cooled, so your cat is most likely to shed to some extent year round. (An analogy: a cat in the wild is like a deciduous tree, dropping old leaves at one time in the fall, but your house pet is like an evergreen, dropping leaves or needles a few at a time no matter the season.)
