falling apart at the seams (5)
I believe the answer is:
ratty
'falling apart at the seams' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for ratty that I've seen before include "character on the river bank" , "Bad-tempered, irritable as a rodent" , "Moley's friend" , "Get annoyed" , "One messing about in a boat" .)
