Here's a clue: they're nothing like the dog days, as far as I can tell.
The kitties are a mess. The colds they had when we got them have turned into upper respiratory infections, for which they're taking antibiotics, and now they have ringworm, so they're coated in a greasy antifungal goo. Better still: the spores can stay active for up to 18 months, so experts recommend steam-cleaning all carpets, upholstery, and curtains, and dousing every other surface with a dilute bleach solution. And did I mention that humans can get ringworm from cats? So now every time I have the slightest itch, I'm sure that I, too, am about to raise my foot and try to scratch my ear off.
We're trying to dwell on the positive: they seem unphased by any of this--are still running around and wrestling with each other and eating like small horses. But honestly, this is not what I bargained for when we adopted these babies. I feel horrible even saying that, but, well--let's just say I'm sending out props to all you real parents of real children who nurse them through illnesses and clean up after them with nary a thought. At least I can shut these two in the basement when they get too skanky.
