Degus should be fed a variety of hays, leaves, flowers, branches and roots. Pellets should only be used as a supplement, not a main food source.
High sugar items like raisins should be avoided as degus are very prone to diabetes
We buy our degus Timothy Hay from https://www.timothyhay.co.uk/
We also love the Ings hay from https://www.hay-and-straw.co.uk/
There are also quite a few nice pet shop hays that are mixed with herbs and flowers
The vast majority of pellets on the market have poor quality ingredients that contribute to gut problems. Pellets should not have ingredients like soybean hulls, wheat feed, soybean meal or molasses
