about 48 in human years
Mature · 7–10 years Middle age; small changes start to matter.
What the mature stage means
A mature cat is roughly middle-aged in human terms. Many stay just as lively, but this is when kidney, thyroid, dental and joint problems can begin, often without obvious signs.
Care tips at this age
- Ask your vet whether blood tests make sense at the yearly check-up.
- Watch for changes in drinking, appetite, weight and litter habits.
- Make favourite spots easy to reach as joints stiffen.
