CatColony
Track every cat in your colony.
Built for TNR volunteers and colony caretakers: ear-tip status, spay/neuter dates, vaccinations, feeding and trapping campaigns — all in one place. Or just log the neighborhood cats you spot.
How it works
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.
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.
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.

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.

Vet PDF export
