Your kitten is growing up
By six months old, your kitten will have reached three quarters of her adult size. But don't be fooled by appearances - she may look like an adult but she won't behave like one (not unlike a teenager!) Play and mischief are very much the order of the day.
You should still be feeding your kitten specially formulated kitten food. Appearances can be deceptive, and she won't be ready for 'grown up' food for some time yet.
At six months old, your kitten should have her last monthly worming dose. From now on, you should worm her every three months (or every six if there’s only one cat in your household) for the rest of her life to protect her from parasites. Remember, if you find out your cat has fleas, it’s important that she’s also treated for worms.
Another thing to think about is brushing her teeth. Hopefully you're already in the habit of doing this a few times a week. If not, start now. Your kitten has all her adult teeth now and they will have to last her for some time. So the earlier she gets used to it, the better.
Between six to 10 months your kitten will progressively reach sexual maturity so if you are not planning to breed from her, you should have your kitten neutered.
When your kitten is a year old, she's officially an adult. Ask your vet about a preventive adolescent health check to make sure she’s developing properly.
Moving to an adult diet
Don't forget, although your kitten will look like an adult from about six months of age, it's advisable to keep feeding her specially formulated kitten food until she reaches her first birthday. Then you can gradually start introducing 'grown up' food like Hill's Science Plan Feline Adult and Hill's Science Plan Nature's Best Adult. However, if your cat has been neutered she can be fed Hill’s Science Plan Neutered Cat from 6 months of age.
