摘要: In spite of the worldwide occurrence domestic cats and dogs, their close relationship with humans, number published papers on free-ranging Felis catus dogs Canis familiaris, is small. The diet both species was estimated in a suburban rural environment July 2002 January 2003. Visual observations scat collection were accomplished along 10 km transect line Campus 'Luiz de Queiroz', University Sao Paulo, Piracicaba, south-eastern Brazil. determined by analysis sterilized, washed, dried sorted scats. Estimated abundances sampled area 81 ( � 4.32) 42 2.96), respectively. Cats more abundant than (t= 3.78, Po0.001, N = 55; t= 8.38, 55, respectively) 6.76, 55), even though there no significant difference between abundance (t 0.82, P= 0.46, N= 55). Invertebrates most commonly consumed item species, followed mammals (cats: 63.24 20.51%; dogs: 57.05 25.15%, respectively). Niche breadth 0.4892 for 0.4463 dogs. overlap almost complete (0.97108). consumption to be 16.76 25.42 kg individual 1 year 2.01 2.9 cats. These data might useful establish management program minimize predation pressure wildlife.
