How accurate is the growth curve?

Growth curves are population averages -- individual pets vary considerably within any breed. The ±15% on-track band reflects this natural variation, so a healthy pet near the edge of 'on-track' is still within a reasonable range. The chart is most useful for spotting sustained trends, not for reacting to a single reading.

When should I stop using the Growth Chart?

The chart is most useful during the active growth phase -- roughly the first 12 months for small and medium breeds, and up to 18-24 months for large and giant breeds. Once your pet has reached their adult size, the Weight Checker and Body Condition Score Calculator are more relevant tools.

My kitten is above-average on the chart -- is that a problem?

Not necessarily. Some kittens are simply larger-framed individuals within their breed. Check that you're feeding a complete kitten formula at the recommended amount, and mention the trend to your vet at the next routine visit if it persists.

Can I use this chart for adult pets?

The Growth Chart is designed for pets still in their active growth phase. For adult pets, the Weight Checker (which compares current weight to the ideal breed range) is the more appropriate tool.

The Growth Chart tracks a growing puppy or kitten's weight against a typical breed growth curve and tells you whether they're on track, ahead, or behind. Here's what the tool is actually measuring.
