CatColony: Cat & TNR Tracker

CatColony helps TNR (Trap-Neuter-Return) volunteers and colony caretakers keep track of every cat they look after — and lets casual cat-watchers log the strays they see around the neighborhood.

WHAT IT DOES

• Track each cat: photo, name, sex, age, coat and markings

• Record ear-tip status with your clinic's left- or right-ear convention

• Log spay/neuter status and dates, microchip IDs and vaccination due dates

• Keep a full medical history per cat — vaccines, surgeries, treatments, vet, cost

• Add behavior and health observations over time

• Group cats into colonies with location, feeder and establishment date

• Log feeding: wet/dry amounts, water refills, who fed and when

• Run trapping campaigns with a step-by-step event timeline

• See colony stats: ear-tip %, spay %, vaccination status and feeding cost

• Export a cat's medical history as a PDF to bring to the vet

• Get reminders when a cat is due for vaccination

• Share a colony with other feeders using an invite code

TWO WAYS TO USE IT

• Managed colony mode — full tracking for TNR caretakers and multi-cat owners

• Neighborhood cats mode — a simple way to log strays you spot, with unlimited cats

WHO IT'S FOR

• TNR volunteers and feral-cat colony caretakers

• Animal rescue and community cat groups

• Anyone feeding or watching neighborhood cats

• Multi-cat households
