Dylan,
I feel you pain on the oven. They turned mine into a dog food storage area. It took HOURS to scrub off charred Eukanuba grease (and of course the turds). It smelled like most people wouldn't believe.

Be careful with that poison - be sure to place it where it can't be accessed by children or pets and be sure to gather the remainder for proper disposal when you're done. My beagle ate some poison while visiting a friend's place and I can tell you it was not a fun experience. It turned out OK in the end - it was some of the newer, less lethal stuff, but it easily could have been it for my best friend. Death by rat poison is horrendous way to go.

Mind you, poison was the right choice for my friend (the non-beagle one), he had a full-on infestation. Rat/mouse poison is dangerous stuff that lasts years and can have unintended consequenses, so it should be used with utmost caution.
