Oddlo

Cats can't talk, so unusual behavior is often the only warning sign they can give — but it's hard to put "something feels off" into words. Oddlo is a cat symptom quick-check tool. Starting from "Does your cat do XXX?", it guides you through behavior categories to find likely causes, red flags that need urgent vet care, and simple at-home checks — all written in plain language, no medical background needed. CORE FEATURES - 16 behavior categories covering diet, litter box habits, coat, and more - Clear "see a vet soon" warnings for urgent situations - Traditional Chinese / English / Japanese / Korean interface - No account or login needed — everything stays on your device IMPORTANT Oddlo is an observation and note-taking tool for pet owners. It is not a substitute for professional veterinary diagnosis. If your cat shows unusual behavior, please consult a vet. The app is free with a banner ad; a one-time in-app purchase removes ads permanently.
