The Mouse That Won't Die

When we moved into our place our landlords had just had an exterminator come to the house. It is an older house and apparently there had been a mouse problem previously. So anyways it wasn't till few months ago that we found signs that we had a visitor, it wasn't much more than a simple mouse turd. So we informed our landlords and they had the exterminator come back and place more bait bags and blocks under the sinks and in the ceiling etc. So we figured this will get the little bugger. Well apparently not cause about 2 weeks later we had just gone to bed when we heard rustling and turned the light on just in time to see the little guy scurry away. But this was the last we heard or saw of it for a while. So we figured he ate some of the bait and was no longer. Well the last few days and nights we have heard it walking up in the ceiling, and this morning at like 5am we were awoken by not only his little feet moving around but also to loud squeaking. It was funny...Chris said "maybe he is squeaking in agony cause he ate some bait and is dying." And I said "yeah right, he is probably up there laughing at us saying....you can't kill me." Who knows, we tend to only here it at night or early morning, so we will see what happens later tonight.
