Gerbil noises?

[KittyGurl]

my two young female gerbils are making that same noise. I have heard them make the noise when they are grooming eachother and my older male gerbil just died today and I'm hearing that noise again.

I'm so sorry about your gerbil

I wouldn't worry about it. It sounds like pretty normal gerbil behavior to me.
My two gerbils would wrestle each other or fight over food sometimes and complain like that.
I would just move them apart or offer them each a treat.
It's just typical sibling rivalry among gerbil sisters.
