Confused tabby's followed around (11)
I believe the answer is:
complicated
'confused' is the definition.
(I've seen this before)
'tabby's followed around' is the wordplay.
'tabby' becomes 'cat' (I've seen this before).
'followed' becomes 'complied' ('comply' can be a synonym of 'follow'**).
'around' is an insertion indicator.
'cat' put into 'complied' is 'COMPLICATED'.
(Other definitions for complicated that I've seen before include "Tricky" , "Not simple" , "consisting of many interconnecting parts" , "Intricate, difficult" , "confused" .)
