Catteries and pet stores differ in their breeding focus, breeding management, professional knowledge, number of cats, health guarantees, service scope, environment, price, cat selection process, and after-sales support.

Catteries primarily focus on breeding specific breeds of cats, with stricter breeding management and health screenings. Owners have in-depth knowledge of these breeds, and their relatively smaller numbers of cats provide a more reliable health guarantee. Pet shops, on the other hand, sell cats and offer other pet supplies and services, and may have a larger number of cats. Catteries are generally more expensive. During the cat selection process, catteries may offer more opportunities to learn about a cat's background and personality, and can provide more professional after-sales support. When choosing a cat, you should consider your own needs, budget, and expectations for the cat.
