What do Marmostes eat ?

  • Wild Marmosets are omnivores – in other words they eat both animal and plant food, insects, spiders, fruit and large amounts of tree gum.


  • It is important to include a multivitamin supplement in captive Marmoset diets.
  • Marmosets particularly need Vitamin D3 with adequate sunlight, some chemicals in their skin are converted to this vitamin.

Although requirements vary with season, sunlight and temperature, a general rule might be to supplement diets with, 250i.u D3 per animal per week in summer and 500 i.u in winter.

Variety is the spice….

  • Food ( particularly fruit and vegetables) should be fresh and also varied to, prevent boredom and should be available at all times.
  • Items like Marmoset pellets are highly nutritious but not very tasty and the discerning Marmoset gourmet may turn up its nose and seek out juicy fruit and vegetables instead.
  • You can normally get around this by feeding pellets in the morning before other foods are offered.
