When do Sphynx cats reach their full adult size?

Most Sphynx cats are close to full adult size by 12 months. Some males continue to fill out with muscle mass until around 15–18 months, but the primary growth phase concludes by the end of the first year.

How much should a Sphynx kitten weigh at 8 weeks?

A healthy Sphynx kitten at 8 weeks typically weighs between 800 g and 1.1 kg. Kittens consistently below this range warrant a veterinary check to rule out growth or health issues.

Should I free-feed my Sphynx kitten?

During the first 6 months, free-feeding a high-quality kitten food is generally appropriate to support rapid growth and meet the breed's elevated metabolic needs. From 6–12 months, transitioning to 3–4 structured meals per day is advisable as growth slows.

My Sphynx kitten looks very wrinkled — is that normal?

Yes. Loose, wrinkled skin is a hallmark of the Sphynx breed at every life stage, not a sign of underweight. Assess growth by tracking weight on a scale weekly, not by visual appearance alone.
