A porridge I cooked for US critter (7,3)
I believe the answer is:
prairie dog
'us critter' is the definition.
The definition suggests a singular noun which matches the answer.
'a porridge i cooked' is the wordplay.
'cooked' indicates an anagram (letters cooked into a new form).
'a'+'porridge'+'i'='aporridgei'
'aporridgei' anagrammed gives 'PRAIRIE-DOG'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for prairie dog that I've seen before include "Underground community member" , "Animal" , "Rodent" , "A ground squirrel" , "North American burrowing mammal" .)
