I'm just curious, would a mouse be able to harm a budgie? I am not getting a mouse any time soon but I like them and was thinking about it since I would like one at some point in my life. I know rats can kill birds but I'm curious about mice. I know it is recommended to keep them separated obviously, but if there was an accident and the mouse got into the bird cage (which is very possible with the bar spacing), would there be any harm?
I am always thinking about scenarios with future pets even though I might not ever get them or simply won't for years. But it makes me curious and since the thought crossed my mind I would like to know now
