Pet insect runs in bread basket (7)

Ross

I believe the answer is:

tantrum

I'm a little stuck... Click here to teach me more about this clue!

'pet' is the definition.
(I've seen this before)

'insect runs in bread basket' is the wordplay.
'insect' becomes 'ant' (ant is a kind of insect).
'runs' becomes 'r' (cricket abbreviation).
'in' means one lot of letters goes inside another.
'bread basket' becomes 'tum' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'ant'+'r'='antr'
'antr' placed within 'tum' is 'TANTRUM'.

Can you help me to learn more?

(Other definitions for tantrum that I've seen before include "Fit of childish temper" , "Childish angry outburst" , "Burst of temper" , "Display of bad temper" , "Hissy fit" .)
