so my sister came up to my dad and said 'i think they budgies are having a fight or something' and so my dad went and checked it out. i was in my room the whole time and heard rattling noises from the cage. i heard my sister panicking. then i heard my sister say '... unless it was a very small mouse then ...' and i didnnt hear the rest. i think maybe one of my budgies got attacked by something. and then my dad said something about strangling. so maybe onoe of the budgies or something else had somehow strangled one of my budgies.
