When is an Oriental Shorthair fully grown?

Oriental Shorthairs reach close to adult size by 12 months. Full muscular and social maturity typically follows by 18–24 months. They do not have the extended 3–4 year growth timeline of some large breeds like Maine Coons.

How much should my 3-month-old Oriental kitten weigh?

At 3 months, a healthy Oriental kitten typically weighs around 900 g–1.3 kg, though individual variation is normal. If your kitten seems significantly below this range, mention it to your vet at the next visit.

When should I switch from kitten to adult food?

Around 10–12 months for most Orientals. If your kitten was spayed or neutered at 6 months, consider transitioning to a post-neuter or adult formula a little earlier, as calorie needs decrease after the procedure.
