One appraises animals like this? Right! (8)
I believe the answer is:
assessor
'one appraises animals like this? right' is the definition.
The definition suggests a singular noun which matches the answer.
'animals like this? right' is the wordplay.
'animals' becomes 'asses' (I've seen this before).
'like this?' becomes 'so' ('like so').
'right' becomes 'r' (common abbreviation).
'asses'+'so'+'r'='ASSESSOR'
Can you help me to learn more?
(Other definitions for assessor that I've seen before include "One values property" , "Official to evaluate property" , "Maker of valuations" , "Person who tests" , "One who rates for tax" .)
