It seems the only thing todays cats will hunt for is the can opener.
Caught one of the bigger mice I have seen(no it wasn't a rat-had them on the farm)with a good old Woods spring trap baited with peanut butter. Forgot I had set the trap-found it quickly after getting home from Vegas!
My dad used to use Hungarian Sausage-peanut butter works best.
If you use the anti-coagulents like Warfarin make sure your pets don't get into it-even a small wound won't stop bleeding. One other drawback is while they are drying out you may be playing "Where's That Smell Coming From".
If you kill a family of mice and they choose to die inside your dining room wall-don't invite anybody for supper for a week or so-Just Sayin-Been there-Done that- Didn't like it.
