It’s the millipedes. They live in the bathroom which is used by just me & 2 cats. They are so small, a dot shaped like an oval & they have all these long, skinny legs, skinnier than a Daddy-long-legs spider & they keep tripping over themselves & it’s so hard for them to get any place. They come out at night, when the cats are asleep & gather in the corner behind the door & at first I thought I was seeing spots before my eyes, but they are real & they are sad because they can’t even climb all the way to the top of the wall where some cousins live on the ceiling. I am very careful not to step on them, but I’m not so sure about the cats.
