Some cats are great mousers, others not so much. Mice will enter your house for two reasons, food and shelter. So, first off, make sure you have nothing they can get into to eat. Everything needs to be enclosed in cupboards, and better yet, in plastic containers in the cupboards. The one time we had mice, we discovered an old bag of grass seed in the basement that got pushed under a workbench. We had no idea it was there, but the mice found it!
Once you are sure that there is no available food source for the mice, you need to try to figure out how they got in. Seal up as best you can (and remember, mice are chewers). Finally, you have to get rid of the mice in your home. I am a live trap and release kind of girl, but depending on where you are that might not be feasible. Do not use poison, because first of all, if a mouse dies from the toxin, you may not be able to get to it. And that will REEK! Also, if a poisoned mouse gets out and dies outside, that will pose a serious risk to any animal that ingests the remains. Ugh. I also don’t like glue traps. The kill the animal slowly, and I think they are terribly inhumane. The least inhumane trap would have to be a snap-trap, but they are not foolproof. If it doesn’t get the mouse just right, it won’t kill it. But when they do, the mouse will be killed instantly.
If you really want to be rid of the mice, I could loan you my Jack Russell Terrier. But he’d probably destroy your house in the process. He won’t stop where prey is concerned. :mrgreen:
