Why Is My Cat Losing Weight Suddenly?

A small change in body weight may be hard to notice at first, especially in long-haired cats, but sudden weight loss should always be taken seriously. If your cat looks thinner, feels lighter when lifted, or the spine becomes easier to feel, there may be an underlying reason.

Weight loss happens when the body uses more energy than it receives, or when food is not being properly absorbed.

A reduced appetite quickly affects body condition.
