Prepare for encounter with contrary cat that has run inside (4,2)
I believe the answer is:
warm up
This clue might be a double definition.
'prepare for encounter with contrary cat that' is the first definition.
'warm up' can be an answer for 'prepare for' (I've seen this before). I'm not sure about the rest of the definition.
'run inside' is the second definition.
'warm up' can be an answer for 'run' (warming up is a kind of running). I'm unsure of the 'inside' bit.
'has' acts as a link.
Can you help me to learn more?
(Other definitions for warm up that I've seen before include "Rehearse" , "Athletes do it" , "Practise" , "heat" , "Prepare for" .)
