When is a Himalayan cat fully grown?

Most Himalayans reach their full adult size by 12 months, with some individuals continuing to develop in body substance until about 18 months. Adult weight is typically 3–5.5 kg (6.6–12.1 lb).

My Himalayan kitten's coat looks patchy between 4 and 8 months. Is that normal?

Yes — this is a normal transition from the fluffy kitten coat to the adult longhair double coat. The adult guard hairs grow in at a different rate than the undercoat, creating a temporarily uneven appearance. It resolves as the adult coat matures.

When should I switch my Himalayan from kitten to adult food?

The transition is appropriate around 9–12 months. Make the change gradually over 7–10 days by increasing the proportion of adult food in the mix each day. Reduce overall portions at this transition to match lower adult calorie needs.
