This ties in very will with the TWRL (TEST Weapons Research Lab) Cat Launcher.
There are still some issues with the design, like the Ammo Storage Boxes - To contain an average magazine of 12 cats, the box is currently the size of a lonly spinsters suburban home, and that is not to mention the food and water requirements of having live ammo and the biggest issue: will the ammo storage box need a dedicated set of entertainments items like balls of wool and laser pointer to keep the cats entertained until they are fired? And as for the automatic loading system, damn will those cats not stay still.
To be honest, I think this is one TWRL design that might not get to market.
