Purveyor of provisions for feline queens (7)
I believe the answer is:
caterer
'purveyor' is the definition.
(I've seen this before)
'provisions for feline queens' is the wordplay.
I cannot really see how this works, but
'feline' could be 'cat' (cat is a kind of feline) and 'cat' is located in the answer.
This explanation may well be incorrect...
'of' is the link.
Can you help me to learn more?
(Other definitions for caterer that I've seen before include "Someone providing food and service" , "Food and drink supplier" , "One providing food and drink" , "Provider of refreshments" , "Refreshment supplier" .)
