People who recently began buying cat food after getting a kitten may be interested in taking part in a study to improve the health and wellbeing of cats.
Researchers at the University of Bristol are seeking out people who have a kitten aged between eight and 16 weeks and then at the ages of six, 12 and 18 months.
Owners would need to fill in questionnaires about their feline companion.
In a statement on the Cats Protection website, Dr Jane Murray, Cats Protection research fellow, explained what study is for.
She wrote: "Many of the causes of common behavioural traits and diseases of cats are unknown and it is hoped that this study will help us to improve the health and welfare of cats in the future, for example by identifying ways we can reduce the risk of common problems such as obesity and aggressive behaviour to people and other cats."
Cats Protection was set up in 1927. It now has over 250 volunteer-run branches that help over 215,000 cats every year.
