When I approached my apartment building yesterday on my way home from spending some time in Seattle, I noticed that the blinds in one of the living room windows were a bit askew. I didn't think too much of it at the time.
After greeting the kitties, who were quite happy to see me, I did a quick tour of the apartment and found everything just as I'd left it.
That plant had been on the sill of the window whose blinds were askew. The second of the two spider plants was still on the sill, though it had miraculously become quite sparse over the weekend.*
Melly very much enjoyed the cleanup process and "helped" by chasing the broom and tracking dirt everywhere. Scarlett, who affected an air of innocence, made it clear that she was quite displeased with me for leaving her to watch over such a terror.**
* Research indicates that spider plants are not toxic to cats, though they may cause vomiting.
** I doubt Melly could have made the jump to that windowsill.
