The rough bands vets tend to use
| Age | General category |
|---|---|
| Under 7 | Adult |
| 7 to 10 | Mature |
| 10 to 14 | Senior |
| 14 and over | Geriatric |
These bands matter mostly for check-up frequency and what bloodwork gets recommended, they're not a statement about how any individual cat is actually doing.
Why two cats the same age can be so different
Breed, weight history, existing conditions, and simple individual variation all matter more than the number on its own. A well-managed twelve-year-old with no ongoing issues can be in a genuinely better position than an unmanaged eight-year-old carrying undiagnosed weight or dental problems.
What actually matters more than the birthday
A real trend in weight, appetite, mobility and behaviour tells you far more than an age band ever will. The senior checklist covers what's actually worth watching, regardless of which band a specific cat happens to sit in.
Halo is built around exactly that, your specific pet's own baseline and trend, not a generic bracket assigned by age alone.
