This data was gathered as part of a first-of-its-kind program at the University of Bristol in the UK. The Cat Longitudinal Analysis of Welfare Study (CLAWS) collected information from kittenhood through two years about cats adopted from rescue centers to understand how their early development shapes their later health and behavior. Surveys filled out by each cat’s family asked them to report their cat’s body score as well as other information such as feeding habits and behavior information.
