Number and weight of faecal pellets produced by opossums

Caged opossums (Trichosurus vulpecula) were fed on leaves of one or more of their normal food plants and on a pelleted commercial food ration. The number of faecal pellets voided per day (24 hour) was proportional to the amount of food eaten. Opossums maintaining a constant body weight produced 98.3 (± s.e. 3.0) pellets per day, confirming earlier estimates from less natural diets
