Show animals (4)
I believe the answer is:
cats
I believe this is a double definition.
'show' is the first definition.
(I've seen this before)
'animals' is the second definition.

(Other definitions for cats that I've seen before include "Siamese, Persian etc" , "Musical (felines?)" , "1981 Lloyd Webber musical" , "Carnivores - stage musical" , "Musical; jazz fans" .)
