## What is 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 and observation journal. 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.

SYMPTOM CHECK
- 16 behavior categories covering diet, litter box habits, coat, and more
- Clear "see a vet soon" warnings for urgent situations
- Log symptoms, severity, and notes as you notice them

SENIOR CARE
- 26 questions across 8 areas to track subtle changes in vocalization, interaction, sleep cycles, and more
- Fill in one category or one question per page, and save drafts to finish later
- See how each answer changes over time — no scores, no automatic judgments

CAT HARMONY
- Record how many litter boxes, food bowls, water bowls, elevated beds, and scratchers you have, and where they are placed
- Step-by-step new-cat introduction plans with notes and observations
- Log interaction events between your cats to review later

VET SUMMARY
- Keep separate records for multiple cats
- Combine symptoms, senior observations, and interaction events into a 30, 90, or 180-day summary; copy the text or create a PDF to share with your vet

MORE
- Three interface styles: Lamplit Journal (deep green with amber light), A Room at Night (warm wood with orange light), and Bedside Index (ink blue with moonlight)
- 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.
