What is the smallest machine gun that could possibly operate?

Everyone knows that build a better mousetrap and the world will beat a path to your door, but does anyone see things from the mouse's perspective. Mice really need machine guns to protect themselves against cats, but would a gun this small really work. The Japanese love to minaturise things, but not sure is this is viable.

Thanks in advance for any replies.

My cat is called "Trigger."

Mice better not come knocking on this door again, they will get full barrels next time

Trim... is correct, I think, getting some functional charge and detonator combination that can be made small will be the limiting factor.

Difficult to see how a machine gun would protect a mouse from a mousetrap...

Come on Rojash, keep up! they would shoot the person that put the trap down and then shoot the trap.

Thank for your answers, folks, and no, this was not a trick question. The guns I propose are to protect mice from cats, not mouse traps. If mice are clever enough to make their own machine guns, they should be clever enough to avoid a silly mistake like stepping into a mouse trap. Yes, they would be limited by the amount of cordite in the very small bullets the guns would fire.

As it's well known that mice are hyper-intelligent pan-dimensional beings I suspect they have far more advanced technology available to them.

i love this question!

"they would shoot the person that put the trap down and then shoot the trap."

But doesn't that presuppose that they know it's a trap?

In my experience, they tend to suffer a broken neck, just at the moment of realisation.

Rojash, they have "mouse Trap" written all over them!!

[RATTER15]

This is pretty small.

I'm such a fool - I hadn't realised!
