5 Categories That Constitute Short-tailed Opossum Diet (What Do Short-tailed Opossums Eat?)

  • High quality dry Cat food for adult short-tailed opossum and High quality dry Kitten food for young short-tailed opossum. (see recommendations below)
  • Treats such ainsects, meal worms and cooked eggs (You can get Freeze dried cricket/grasshoppers, super worms. 1-5 bugs a day is okay.)
  • Rodents (They like Baby mice pinkies.)
  • Fresh Food- meat (fish, chicken breast, ground turkey), hard-boiled egg, scrambled egg, small amounts of fresh fruit (e.g. cantaloupe berries, grapes) and small amounts of fresh vegetables (if your short-tailed opossum fails to eat vegetables, blend it with some fruit-e.g. zucchini with kiwi and banana), yoghurt drops. Remember that fresh food goes bad after time and should not be left in the cage, give in the evening and remove in the morning.
  • Water- The importance of water to your Short-tailed opossum cannot be emphasized enough!!! She or he can become dehydrated quickly. Always ensure there is enough clean water in his or her cage. Use a water bottle, you will see recommendations below.

DO NOT give Avocado. It is bad for them.

As you can see above, there is a mention of a young short-tailed opossum and an adult short-tailed opossum. Lets’ make this clear…

  • Young short-tailed opossum:  under 6 months
  • Young adult short-tailed opossum: 6-12 months
  • Adult short-tailed opossum: 12+ months

Again, you can see the mention of high quality!! What does this mean?

  1. Protein content should be 30-40%.
  2. Fat content should be 10-15%.
