CatCareOS

Your cats, fully documented. CatCareOS is one private app for 1 to 3 indoor cats. Each cat gets a full profile with breed, DOB, sex, spay status, hair length, color and markings, microchip ID, insurance policy number, vet, and current weight.

The Health Log tracks every vet visit, FVRCP and Rabies vaccine, medication, parasite prevention dose, dental cleaning, and weight check - with next-due dates and a per-cat weight trend chart that catches silent weight loss early.

Grooming and Claws tracks nail trims, brushing, ear cleaning, and teeth brushing with last-done and next-due per cat and task.

Litter and Hydration applies the n+1 box rule, logs daily scoops and fountain cleans, and flags urination concerns (straining, blood, volume changes) for early CKD, UTI, and diabetes detection. Behavior captures daily 30-second observations with 7-day pattern analysis.

Runs entirely in your browser - no subscription, no login, no cloud.
