Last week, I took a couple of days and went up to the mountains to take care of plumbing problems (sulpher smell in the water and dripping pipes under the kitchen sink) as well as to clean up the damage made by the squirrel.
Last month, my house partners went up to check on how things were after the winter and discovered that a squirrel had come down the chimney, out through the wood-burning stove and into the house. It is amazing how much damage a trapped, hysterical, sooty squirrel can do. There were little sooty tracks all over the living room and kitchen, larger sooty swaths where his tail had lashed, and he had tried to eat his way out the window frame.
Long story short, I haven't cleaned so hard since we moved Jon out of his apartment, end of sophomore year and we wanted at least part of our security deposit back.
So now the plumbing is fixed, the house is clean, and this guy is gone.
