200 adults (100 men and 100 women with a mean age of 58.8 yr.) were interviewed to assess the associations of recollections about their grandparents' and parents' attitudes and their adults' attitudes and behaviors toward pets. Subjects were categorized into Never-owned pets, Always-owned pets, Owned-in-childhood-only, and Owned-in-adulthood-only groups ( ns = 25). Subjects were asked about their present and past ownership and experiences, and the attitudes toward ownership of pets by their grandparents and parents. Although the literature suggests that childhood experiences strongly affect adults' attitudes toward pets, there were no differences in attitudes between adults who had always owned pets and those who owned pets only during adulthood. These two groups had significantly more grandparents and parents who owned pets than did the other two groups. Significantly more subjects who had owned pets only during childhood reported unpleasant experiences with pets than did subjects of the other three groups. Subjects who had owned pets only during adulthood were persuaded by their children or significant others to acquire pets to which they became very attached.
