When do Persian cats reach full size?

Most Persians reach the majority of their adult weight by 12 months of age, though some individuals fill out slightly until 18 months. This is faster than giant breeds like the Maine Coon, which can take 3–4 years to fully mature.

Why does my Persian kitten not have a full coat yet?

The full adult coat doesn't develop until 12–18 months of age. A Persian kitten's coat looks progressively denser through the first year and beyond — this is normal and not a sign of poor nutrition or health.

How much should a 6-month-old Persian kitten weigh?

Around 2.0–2.8 kg is a typical range for a 6-month-old Persian kitten, though individual variation is significant. Males tend to be heavier than females at every stage.

When should I switch my Persian kitten to adult food?

At 12 months. Switching earlier deprives the kitten of the higher protein and nutrient density that kitten food provides for bone and muscle development. Transition gradually over 1–2 weeks to avoid digestive upset.
