Frequently Asked Questions

How accurate are adult size predictions?

Adult size predictions are estimates based on growth curves and current measurements. Individual kittens may vary based on genetics, breed, nutrition, and health. These estimates provide a general range to expect.

When do kittens stop growing?

Most kittens reach their full adult size by 12 months of age, though some large breeds like Maine Coons may continue growing until 18-24 months. Growth rate is fastest in the first 6 months.

What are typical growth milestones for kittens?

Kittens typically double their birth weight by 1 week, triple by 3 weeks, and quadruple by 4 weeks. By 6 months, they're usually about 75% of adult size, and by 12 months, they're fully grown.

How can I ensure my kitten grows properly?

Provide high-quality kitten food, ensure they get adequate calories (use our Kitten Calorie Calculator), monitor weight regularly, and schedule regular veterinary check-ups. Proper nutrition during growth is crucial for long-term health.
