Ask most caretakers how many cats are in their colony and you’ll hear a range: “ten, maybe twelve?” That’s understandable, cats come and go, and they’re hard to count. But a real census, tracked over time, is one of the most useful things a rescue can keep, and the trend line matters more than any single total.

What a census tells you

• Whether TNR is working. A colony that’s fully fixed should hold steady, then slowly decline. If it’s growing, you’ve got intact cats or newcomers to find.
• New arrivals and abandonments. A sudden jump often means someone dumped a cat or a nearby colony is spilling over. Catching that early means fewer litters later.
• Proof for funders. Grants and donors want outcomes. “This colony went from 24 to 9 over three years” is a story a spreadsheet of feeding receipts can’t tell.

How to actually count

Photos are your friend. Distinguishing marks and ear tips help you tell individuals apart so you’re not double-counting the gray tabby. Note counts at feeding time when the most cats are present, and record the date every time. One count is a number; a series of dated counts is a trend, and the trend is what you can act on.

The catch is that a hand-tallied census goes stale the moment a cat is returned, adopted, or lost. Purralytics saves every update as a dated snapshot and adjusts the count automatically when a cat’s status changes, so the trend is always current and always there when a funder asks.
