Are the cat photos real or AI-generated?
All cat photos are 100% real, sourced from The Cat API (thecatapi.com), which aggregates user-submitted and curated cat images from around the world. No AI-generated images are used — every photo features an actual feline friend.

Why do cats purr? Is that covered in the facts?
Many of our cat facts explore feline behavior including purring, kneading, and vocalizations. Scientists believe cats purr not only when content but also as a self-soothing mechanism — and some studies suggest the frequency of purring (25-150 Hz) may even promote healing. Keep refreshing to discover more fascinating insights!
