Lately, there were problems with mice getting in through the walls
behind the kitchen counters. I found  droppings on the counter, in
drawers and three dead mice in glue traps. I clogged up the gaps
connecting the counter to the wall. Still a big hole inside the conter
where the water pipe connects to the sink. Can't reach it. Glue traps
wre empty for the past week and no droppings on the counter, so I
thought I had plugged up the mice entry point into the house.

Well anyway, last night, after finishing watching basketball, I turned
off the lights and was ready to snooze, and I hear my cat jumping
around and I hear loud pitched squeaking noises. I thought it was
perhaps a bird...they sometimes get in throug the laundry vent that
opens outside.

Well I investigated, and under the tv, I shined a flashlight and see a
small , scared mouse. My cat had lost track of it , and I had to keep
poiting it out. She kept purring and rubbing against my arm and
flashlight. I had to refocus her to the task at hand.She cornered it
in a milkcrate. She pawed and poked at it. I went to the kitchen to
look around her food dish for mice droppings. Two or three days ago,
she was pawing at something around there, and I assumed it was a bug,
but it may have been the mouse. Unfortunately, I saw a couple of mouse
droppings there.

I went back to the cat, which had retrieved the mouse in her mouth and
brought it to me. It was barely alive...probably being scared to
death. I disposed of it in a cigar box, an sprayed lysol on the area
she dropped the mouse upon, and wiped up.

I spent the rest of the night looking for mouse droppings from the
kitchen to the room with the tv. Yuck, I found a dropping under the tv
tray, and more in the kitchen. I will have to spend the entire day
looking for mouse droppings in the family room, and possible living
room and sweep up.

I gave her lots of tuna flavored treat this morning to reward her for
her first kill.  A few days ago, I berated her for snoozing on the job
while the mice were partying on the counter top. Well she suprised me
big time.

End of story. Rest is about investigative work. Nothing to do with my
cat.

Now I have to find out how the mouse got in. The kitchen counters
don't snugly/tightly fit against the wall. The mouse possibly went
through the big hole in the wall where the main water pipe goes to the
sink and escaped through the side, which I had not plugged up.I only
plugged up the gaps in the top of the counter. ANother possible entry
point is the hole in the wall where the laundry water pipe enters the
house. I didn't see any mouse droppings in that area, so I think I can
safely eliminate that part.

in order to get to the hole in the wall where the main kitchen water
pipe comes into the kitchen , i would have to employ a midget. Not
possible to reach it with my arms. Are there any products out there
where I can spray or apply, which will harden and fill up a large gap
in the wall? Has to be from long distance

Thanks
