FAQs

Is the 7-year rule accurate for cats?

No, the 7-year rule is a myth. Cats age faster in their first two years. A 2-year-old cat is about 24 in human years, not 14.

When is a cat considered senior?

Cats are generally considered senior at 11 years old, which is equivalent to about 60 human years. At 15+, they are considered geriatric.

How long do cats typically live?

Indoor cats live 12-18 years on average, with some reaching their early 20s. Outdoor cats have shorter lifespans due to environmental risks.

Do different breeds age differently?

While the aging formula is similar across breeds, some breeds like Siamese tend to live longer, while others like Maine Coons may have shorter lifespans.

What changes should I expect in senior cats?

Senior cats may experience reduced activity, changes in sleep patterns, weight fluctuations, and may need more frequent vet visits and dietary adjustments.
