Movement that's annoyed feral cat taking time out (7)
I believe the answer is:
flounce
'movement' is the definition.
(flounce is a kind of movement)
'annoyed feral cat taking time out' is the wordplay.
I cannot quite see how this works, but
'cat' could be 'ounce' (ounce can mean a snow leopard) and 'ounce' is found in the answer.
This explanation may well be incorrect...
'that's' acts as a link.
Can you help me to learn more?
(Other definitions for flounce that I've seen before include "Edgy material" , "Move in a pet" , "A ruffle; walk (out) in huff" , "Strut" , "Frill; walk affectedly" .)
