Plain unsalted broth can be a small moisture boost for cats. Typical human soup is different: most recipes and canned soups bring onion, garlic, and salt, which make them a poor choice.
When broth is the safer option
If the liquid is truly plain, unsalted broth with no onion, garlic, or seasoning, a little spooned over food is usually the safer path. Keep it as an add-on, not a meal replacement.
Why most human soup is a bad idea
Soup made for people often contains onion, garlic, leeks, chives, stock cubes, heavy salt, or cream. Those ingredients are not cat-safe, and even “just a sip” of a seasoned soup is not something to encourage.
What to do instead
If your goal is more moisture, use water or a cat-appropriate wet food topper.

If your cat already ate some
For a tiny taste of plain broth, watch for vomiting or diarrhea. If the soup was seasoned, especially with onion or garlic, call your veterinarian sooner rather than later.
