cats

Oh interesting. Were you worried about bleaching your brows so close to your eyes?

Yes a month doesn't seem very long.

I can't find any more specific info on the mourning itself.

Except now I see from the same source that when their dog died, egyptians shaved off all the hair on their body. Huh.

Herodotus too, so grain of salt:

"And in whatever houses a cat has died by a natural death, all those who dwell in this house shave their eyebrows only, but those in whose houses a dog has died shave their whole body and also their head."
