How it works

1

Add your cats and colonies

Snap a photo and record ear-tip, sex, spay/neuter status and markings. Group cats into colonies with a location and a feeder.

2

Log what happens in the field

Feedings, vaccinations, medical events and observations. Run a trapping campaign as a clear timeline from trap set to release.

3

See progress and share

Watch your colony's ear-tip and spay percentages climb, export a vet PDF, and invite other feeders with a code.

Features

Ear-tip tracking

Record ear-tip status with your clinic’s left- or right-ear convention so the indicator matches the field.

Spay / neuter & vaccines

Track fixed status and dates, microchip IDs, and vaccination due dates with reminders.

Medical history

A full timeline per cat — vaccines, surgeries, treatments, vet name and cost.

Observations

Log behavior and health flags over time to spot a cat that needs attention.

Colonies

Group cats by location with a feeder, establishment date and notes.

Feeding log

Record wet and dry amounts, water refills, who fed and when — with optional cost.

Trapping campaigns

Plan and log a TNR drive as a timeline: trap set, caught, clinic, recovery, release.

Colony stats

Ear-tip %, spay %, vaccination status and monthly feeding cost per currency.

Vet PDF export

Export a cat’s medical history as a clean PDF to bring to the vet.

Shared access

Invite other feeders to a colony with a short code.

Neighborhood mode

A simple way to log strays you spot day to day — unlimited and free.

On your device

Your cats, colonies and logs stay on your phone. No account required.

Pricing
