Rodents cooler in student accommodation? (7)
I believe the answer is:
dormice
'rodents' is the definition.
(dormouse is a kind of rodent)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for dormice that I've seen before include "Furry animals" , "Small field rodents" , "For these heavy sleepers" , "little things?" , "Little hibernating rodents" .)
