Gutsy pets? (4)
I believe the answer is:
cats
'pets?' is the definition.
(cat is a type of pet)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for cats that I've seen before include "Feline mammals" , "Popular musical" , "Jaguars, say" , "Musical (felines?)" , "Famous feline Lloyd Webber musical" .)
