Ontogeny of individuality in the domestic cat in the home environment.
The behaviour of house cats Felis silvestris catus from nine litters was recorded at 4 months, 1 year and 2 years of age, in their home environment immediately after meals fed by their owners. We extracted by principal components analysis four elements of 'behavioural style' that were consistent from one age to another: based upon behaviour patterns that were most heavily loaded on each component, these were labelled as Staying Indoors, Rubbing, Investigative and Boldness elements. The Staying Indoors and Rubbing elements are similar to two aspects of behavioural style identified in a previous study of adult cats; the Boldness element, possibly coupled with the Investigative element, may be similar to the shy/bold continuum identified in controlled studies of cats and other species. Four-month-old male cats were the most likely to Stay Indoors; the Rubbing element increased with age in the majority of individuals, both male and female. Littermates tended to be similar to one another in Rubbing (at 4 months) and Boldness (up to 1 year). A positive effect of handling received during the first 8 weeks of life was detected for Boldness at 4 months of age. Copyright 2001 The Association for the Study of Animal Behaviour.
