First, on the coldest night of the winter so far, my furnace is acting up. I realized it was down to 55 or so and looked at it; it was flashing a diagnostic code that said the flame sensor wasn't working. I reset it and it turned on and warmed the house up just fine, but now it's flashing the code again.
And second, I discovered that Meg is leaving bloody tracks. She's been licking her left rear paw a lot, and she has some swelling in the base of the main pad up between the toes. It appears to be very aggravating because when I hold the paw she tries hard to lick it and licks me if I won't let her get to it.
