A few weeks ago we had several mice in the house & all but one were quickly caught.
The remaining mouse would scare my 2 budgies of a night,climb a step ladder close to the cage where seed was spilt etc.
Although the mouse is now gone one of my 2 budgies is scared of bedtime.
He whimpers when it gets dark,when eating and at bed time he panics and whimpers greatly.
Only calms down when is sat with and spoken to but whimpering returns when we leave the room and we don’t want to introduce any habits etc
