rumbling/purring

[amber20921]

my older guinea pig is walking round the cage while rumbling when i went to see them today , why is this ? shes never done it before , she seems fine and shes getting on with the other piggy so why is she doing it ?

My girls do the rumbling thing when they are in season. Sometimes they seem to have stronger seasons than others. Hormones, eh.
