Strange Noise?

[LittleGems]

Hey,
I was just hand feeding Bella and stroking her back with some pressure because I’m pretty sure she likes it and she made this noise which was like ‘Brrrr’ sort of like a cat pur but a bit different. Anyone know what this is?

Probably not a bad noise, as I recently found out from my guinea lady piggy who just hit puberty, maybe she is in heat and the back pressure makes her think you are a male piggy in the mood for love? Next she will pee on you and shake her behind so weird but natural insticts!
