Turns out the afore-mentioned squirrel had a sibling, which died in the wall in the kitchen. When Chris began taking down the cabinets, he ended up having to pull the soffit down. Then, because the ovens were jammed into the corner of the kitchen, we decided to tak the weird corner out- which was just the back side of a closet. A closet we never used because it had a really BAD smell. We thought the smell was mouse urine, and had planned to rip everything out the there anyway.
So, as soon as Chris knocked a hole into the bottom of the drywall, dead animal smell poured out. It was awful. Obviously, the poor critter I'd heard in the wall the week or two before had died. We put our respirators on and opened the whole corner.
The bottom was about 4 inches deep in bones, some tiny and old, some still in a decaying body. Ick. I was sad for all of the animals that had suffered in that wall. They came in the hole in the ceiling, and once in the smooth drywall, couldn't get out.
We opened it up into the closet, and removed all drywall and studs. The smell had permeated everything.
Now it's re-done, but missing the stupid corner. Chris had drywalled everything in, and we sanded and primed the cabinets yesterday. Don't you want to know waht colors I picked??
More to come, and hopefully not bones!!
