Two Dwarf Mongoose Pups, each the size of a chocolate bar, have been spotted enjoying the September sunshine in Chester Zoo. Squeaks were heard by the keepers three weeks ago but the pups were not seen until they ventured outside in the Mongoose Mania enclosure. With a diet of mice, locusts and meal worms, this species normally live to about 10 years old and can grow up to 12 inches long. Dwarf Mongoose Pups are the smallest of all African carnivores and normally deliver one to six pups. The adult pair has been in the zoo since 2009. They were moved to the Mongoose Mania enclosure in March this year.
