Why rodents eat / nimble on everything

307 viewsBiologyOther

A dormouse in my house ate a MVS (mechanical ventilation system) sheath away like it was cheese or something to eat, same for glass wool in the attic; but from what i understand dormouses / mouses don’t use those to make a nest or whatever, so why do they munch on plastic / polystyrene ?

Thanks 😊
(Its about biology i guess ? sorry for the flair if thats not right)

Like our fingernails, rodent’s teeth do not stop growing. They don’t have opposable thumbs to operate nail clippers so they need to constantly chew on things to wear down their teeth.
