A good quality kitten food will provide for all their needs. Kittens become cats around 9-12 months old and can be fed an adult or maintenance diet. We would strongly recommend that a vet has actually assessed your cat prior to making this decision, a vet of pet care specialist should be able to advise.
It is also important to remember that when you do transfer your kitten from a growth or kitten food to an adult food then remember to do so over a period of 7 days. Gradually introducing the adult food to the kitten food over time to allow the kitten's tummy to adjust.
For a healthy, happy cat, you need to keep it at the right weight throughout its life. Being overweight, or indeed underweight, can lead to serious health risks. It is good to get into the habit of checking your pet on a regular basis. The Cat Size O-Meter is the perfect tool to do this. We recommend checking your cat's body condition twice a week using the Pet Size-O-Meter from kittenhood to increase the chances of your cat living a long and healthy life.
