Lolli has always growled/grunted when she gets fed. It’s her “back off” sound. She used to growl all the time when Eddie was alive and she’d have to push her way to get to the treats/food. The “pushing” was normal rabbit/animal “lemme have some!” behavior when you are feeding 2 or more pets. Now she mainly only growls when I give her pellets. I don’t have any clue why. She feels the need to let the world know they are HER pellets and to BACK OFF! 

Well I bought her some Oxbow veggie treats. She LOVES her oxbow treats. And I like them cause I am much able to control the amount she gets rather than the random pinch of oats. lol Tonite, I gave her a treat and she growled. 
She has NEVER growled when she’s gotten treats except sometimes when Eddie was alive.
Anyone else’s bunnies get all growly about treats? Just curious.
Maybe it was her “thank you”……………………………………………….DOH! Oh yeah, rabbitude does NOT involve gratitude. LOL
