Sorry to inform you, but when degus repeat that sound rapidly, it means that they are trying to alert you and the other degu's that they are in danger. This can be caused by them seeing something alarming ( A bird trying to get in and eat them ) or just them being scared of something.
do you know the reasons of this sound? have two male degus and one of them doing exactly this noise sometimes for like 30 minutes non stop.
I heard that it is a noise used by male to inform other male that it is his group. It's something like territory alarm for eventual competitors.
