The Goal: A Stable Colony

Effective colony management aims to achieve and maintain a stable, healthy population. This means:

  • All cats are spayed/neutered (100% sterilization rate)
  • Regular food and water are provided
  • Adequate shelter is available
  • Health issues are addressed promptly
  • Newcomers are identified and TNR'd quickly

A well-managed colony will gradually decrease in size over time through natural attrition, while the cats that remain live healthier, more comfortable lives.

Note

Studies show that TNR reduces colony populations by an average of 66% over time, while improving the health and behavior of remaining cats.

Daily Caretaking Routine

At Each Feeding:

  1. Count the cats and note who's present
  2. Observe each cat's condition
  3. Put out fresh food and water
  4. Remove any leftover food after 30 minutes
  5. Check shelters and feeding stations for damage
  6. Note any new cats or missing regulars

Weekly Tasks:

  • Clean and sanitize food bowls
  • Check water sources
  • Inspect shelters for needed repairs
  • Update colony records

Keep It Consistent:

Try to feed at the same time each day. Cats thrive on routine, and consistent timing makes it easier to notice when something is wrong.

Handling New Cats

New cats may join your colony from time to time. Quick action is essential to prevent population growth.

Identifying Newcomers:

  • No ear tip (universal sign of an unaltered cat)
  • Unfamiliar appearance or behavior
  • Other cats may react defensively to the new arrival

What to Do:

  1. Document the new cat (photos, physical description)
  2. Determine if they're feral or potentially lost/owned
  3. Arrange TNR within 30 days if possible
  4. Add them to your colony records once TNR'd

If a Cat Might Be Owned:

  • Check for collar or ID tags
  • Have them scanned for a microchip at TNR
  • Post on local lost/found pages before TNR
  • Some areas require a holding period

Tip

Try to TNR new cats within one month of their arrival. Female cats can become pregnant quickly, and even one litter sets back your sterilization goals.

Documentation Best Practices

What to Record:

  • Photos of each cat (for identification)
  • Physical descriptions (color, markings, size)
  • TNR date and clinic used
  • Health notes and veterinary visits
  • Behavioral observations
  • Date first seen and last seen

Why Documentation Matters:

Good records help you:

  • Track population changes over time
  • Identify cats needing medical attention
  • Prove responsible management to authorities
  • Coordinate with other caretakers
  • Demonstrate TNR effectiveness to skeptics

Tools:

Use whatever works for you - a notebook, spreadsheet, or app. The key is consistency and keeping records up to date.
