I've never gotten any of those kinds of toys, as they have honey in them. I thought that would be bad for Degus, as it's sweet.
Degus aren't well known in most places. So that makes it hard to know their needs. Most people have never heard of a Degu, and therefore know nothing about them. They don't imagine that a Degu has special dietary needs, so don't look into it before caring for Degus. Hopefully, with time, more information will be readily available.
They do make great pets, and I'm so glad yours are getting acclimated, and are making friends with you! My favorite feeling in the world is having Imana sit on my shoulder and groom my ear. They are fantastic little guys!!!
