my uncles black widow catapult once did its job of keeping cats out the garden, it didn't come back after that rock hit its head either.

but seriously, i like cats, my family however doesn't, my family treat cats like you would treat mice.

my aunt cuts up a sponge into small chunks and soaks it in gravy for cats to eat if they come to the garden, I believe this kills them.

me? i just throw them around onto soft stuff and occasionally fight them with a stuffed monkey, they seem to enjoy that, i like em, which is strange because i'm the only person in my family (mother and fathers side) who likes cats, the rest of them are black belts in cat genocide.

why not get loads of mouse killing devices instead of relying on a cat to do the work?

or some sort of poison gas dude to go over your garden.
