OJ, i know this might sound a bit daft, well mental daft actually and everyone on the thread might fall off of their chairs with their mouths wide open. But what about a cat? If you really dont like mice and cant be doing with the traps, the cat will get the ones you have and any others should think twice. I know you have so much on your plate right now that a cat would be the LAST thing on your mind, but maybe a rescue moggie, less hassle than a kitten to get settled and something for the kids to take the edge off things?
Nah, its a shit idea, i'll post it anyway, so you can laugh hysterically and rock back and forth at the ridiculousness of it.
