Diet And Requirements 

Harvest mice are scavengers in the wild and eat pretty much anything and everything they can find, luckily for them the fields where they come from have a plentiful supply of goodies they love. That being said it its a terribly hard task to create a great quality mouse food. I use millet sprays in my cage design and they love to climb them and eat them. For my mixture I use the following in a jar for my mice. Don't be fooled though they are very hungry mice! Trust me my mix I never get any waste.  The best harvest mice food Component's are as follows:

  • A Good Mouse mix- This is a great base for a food. (Mr Johnson's Supreme mouse) 
  • Dried Mealworms - Harvest mice LOVE insects and mealworms are a must.
  • Dried Fruit- It's a great idea to add a little sweet into their diet but not too much.
  • Dried Flowers- To simulate things they would find in the wild.
  • Dried Carrot, Parsnip and Pea Flakes - They need to get their 5 a day too. They love it. 
  • Grains- I like to add extra Barley, wheat or groats to the mix, Whatever i have spare. 
  • Bird Seed- Harvest mice love small seeds in their food, i normally add budgie seed and some wild bird occasionally 
  • Beaphar Vionate powder - I add this powder to their food to make sure they get all the vitamins and minerals they need especially when they are as small as they are. 

Housing And Temperament 

Harvest Mice are very easy to create a great looking enclosure that they will thrive in. It's best to put them in a tank with a secure mesh lid to provide lots of ventilation and air flow, make sure that tank is secure though! They are escape artists when they want to be.  It's best to go all natural when creating their home. I start with a hollow cork stump that is somewhat a centrepiece  in my tank. This doubles as a great nesting area to help them feel safe and they love to climb the log and hide inside. Harvest mice are good climbers and love to climb branches and bridges to get high, I use hazel branches to create a network of  sticks and branches to get around, Its unbelievable how good they are at climbing they really are acrobats.  These Mice require lots of hiding spots that double as nesting areas, I use grass woven nests, coconut halves, and bamboo nests. For the substrate in the tank I use reptile dirt mixed with bark chips, and coconut fibre this makes a nice looking but versatile floor covering that keeps with the natural theme.  Harvest Mice are lovely looking mice and something very different from your average fancy mouse in a pet shop, they are quite timid mice to begin with however once they have become used to their environment and their keeper they soon become very calm and curious little guys although they will never tame down. Harvest mice can be housed as a large colony and wouldn't fight if the enclosure is big enough for them.


Harvest mice are really wonderful characters and make really good exotic pets and although they need a bit more care than a usual mouse its entirely worth it.  Once you have created an exciting, adventurous and safe environment for your mice they really will be a joy to watch and care for. I wouldn't recommend these mice to a new hobbyist as they do have very specific care needs and would be described as an Exotic but not as complicated as African Grass Mice care. Overall these one of a kind critters are a Joy and would be an asset to any good mouse enthusiast's collection.
