Keeper in grounds stopped by a beast's cry (4,6)

Ross

I believe the answer is:

game warden

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

'keeper' is the definition.
(game warden is a kind of keeper)

'grounds stopped by a beast's cry' is the wordplay.
'grounds' becomes 'garden' (garden is a kind of grounds).
'stopped by' indicates putting letters inside (I've seen this in other clues).
'beast's cry' becomes 'mew' (I can't justify this - if you can you should give a lot more credence to this answer).
'a'+'mew'='amew'
'garden' going around 'amew' is 'GAME WARDEN'.

'in' is the link.

Can you help me to learn more?

(Other definitions for game warden that I've seen before include "Reserve keeper" , "reserve worker" , "One employed to protect rhinos, say" , "Ranger" , "Wild animal guardian" .)
