How fast should a Sphynx kitten grow?
Sphynx kittens have an elevated metabolism and therefore higher energy needs. With no fur for insulation, they lose heat faster — adequate food and warmth are critical. Weight should be checked daily.
When do Sphynx cats stop growing?
Sphynx cats typically grow for 36 months before reaching their full adult weight.
Red flags: When to worry
- Shivering or feeling cold despite a warm environment
- Weight below the minimum curve due to elevated energy use
- Skin irritation or rash combined with weight loss
- Less than 10 g daily gain in the first 4 weeks
