MyCatIsFat is a small, free, ad-supported website with a very focused purpose: upload a photo of your cat, let AI judge the cat’s body-size tier, and get a humorous roast in return. The site supports jpg, png, and webp files, with a maximum size of 5MB per image, and it is only intended for cats. Results use a five-tier scale ranging from relatively slim to something like “Absolute Unit,” and users can save, copy, share a link, or regenerate a different roast.
The site clearly discloses that it uses Anthropic’s Claude. The workflow sends the uploaded cat photo to the model, which evaluates the cat’s body shape based on prompts and generates roast copy in real time, rather than relying on prewritten templates. Its strengths are that it is lightweight, instant, and highly entertaining, while also giving owners a brief reason to consider whether their cat might be overweight. That said, the site is also upfront that the same cat may be rated differently across repeated attempts, such as tier 3 versus tier 4, and long-haired cats may be misclassified as fat because of their fur volume. As a result, the output should not be treated as a medical conclusion.
The site has no accounts, app, email funnel, paywall, or Pro version. Its business model relies on ads such as Google AdSense to cover Cloudflare hosting and Anthropic API costs. On privacy, the text explicitly promises that uploaded photos are not stored, data is not sold, and cat photos are not used to train AI; however, the images are sent to Claude/Anthropic for evaluation. The operator appears to be an individual rather than a company. Users can contact them by email, and the site says a real person will respond, but the level of support is clearly not enterprise-grade.
The main advantages are that it is free, easy to use, requires no registration, has clear privacy commitments, and combines AI image understanding with internet meme culture in a fairly natural way. The downsides are that the pages contain ads, the feature scope is narrow, it only supports cats, there is no API or integration, and it cannot replace a veterinarian’s body condition scoring. It is suitable for cat owners, pet content creators, and users who want something shareable for social media. If a cat already has obvious weight or health issues, the owner should consult a veterinarian directly.
The crawled text does not provide information about access from mainland China, ICP filing, payments, or network availability, so its accessibility status can only be marked as unknown. Since no payment is required, payment availability is less of an issue. Alternatives include in-person veterinary checkups, body condition scoring at pet hospitals, pet health management apps, or general-purpose multimodal AI tools for non-professional image analysis.
