Sometimes kittens are fun.
Other times they think your skirt is a toy, and that biting your feet is a good thing. Then when you bend over in the dark bedroom to extricate the kitten from your skirt, you bash your chin on the metal frame of your laundry hamper. Then you cry because it hurts and you've only had about four hours of sleep because the kitten kept bringing you her toy with the bells on it while you were trying to fall asleep, and when you shut her in another room all you could hear was the kitten crying like someone was killing her.
Companies should let people take leave when they get kittens. They could call it 'cat leave'.
