Love animals, hate mice!! just kill the little *******! Have you any idea the decease then can transport - never mind the fleas?!?!!? We had to get cats because of the mice round here.
In the middle of the night when the cats bring them into the house to play with, I've now got no worries about getting up from bed and going to kill the wee *******! Put the clock back 10 years and I would have run a mile from 1!
Would you think twice about killing a fly?? NO! Do you want a fly walking over the food you are about to eat? NO! So why would you feel bad about killin a mouse that has probably ****** over ALL your dishes etc, that you eat off??
Maybe your cat brought it in, but then again, maybe they have their own route into your house, = ever thought about that?? So do you want all 'their' mates following?? Don't think so. never mind the humane crap - - kill it!!
