I have a mouse in my house, apparently it is somewhere in my vents that run under my house. I took one of my vent covers off so I could see if I could see it running around down there since most of my vents are long straight shots. While I went to look for a flashlight, one of my cats decided she wanted to go exploring herself, and she got stuck (and by stuck I mean she got in, but could not figure out how to get out again). So I tried coaxing her out every way I could, eventually she parked herself in the vents, too scared to move...directly under my furnace. I just spent the past few hours taking my furnace apart, all the way down to having to take the heating elements out of it, and the blower vent so I could access the portion of the vent she was all to ready to make her new home. Pulling her out soon after, followed by me having to put it all back together. I just hope that when winter rolls around, I got it all back together alright, or else it is going to be a LONG COLD Winter, unless of course my house burns down.
