Rumblestunting?

"Rumblestrutting is a mating and dominance dance performed by wiggling the bottom from side to side while making a deep throated purring noise."
Well my guinea Pig is doing this to my other Guinea Pig when ever the younger one makes a squeeking noise and comes out of her hiding place. As far as I know they are both females, Im thinking about taking them to a vet to get the sexed just in case. Because From what I have examened they are both girls. o_o

Have a look at this sexing page https://www.cavyspirit.com/sexing.htm - if you're not 100% sure about their gender, then definitely get a vet or experienced cavy owner to make sure.

Both boars and sows will rumble and mount one another, so I wouldn't worry about that in itself, but it is important to make sure you don't have a breeding pair, and pet shops are notorious for getting it wrong.
