W. Newton A1 Tom Stack A1 R. E. Blair A1 J. C. Keel YR 1981 UL http://bjgp.org/content/31/233/740.abstract AB The incidence of pica in pre-school children was investigated by studying 192 children attending a general paediatric hospital clinic and 69 attending a general practice surgery. The incidence of pica was twice as common in those who kept pets in both study groups. Half of the pet-keeping children with pica had eaten their pet's food. Imitative behaviour is suggested as a probable cause. Pet-keeping compounds a child's risk of infestation not only by providing close contact with a reservoir of enteropathogens but also by encouraging pica.
