I believe the answer is:

cat person

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

'animal lover' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.

'pet acorns confused' is the wordplay.
'confused' indicates an anagram.
'pet'+'acorns'='petacorns'
'petacorns' anagrammed gives 'CAT PERSON'.

Can you help me to learn more?

I've seen this clue in the Sydney Morning Herald.
