Emerald the Terrible seems to be settling in. And Terrible, really, she isn't. In fact, she's turning out to be one of the sweetest little bits of felinity I've ever seen.

Her hissing episodes are few and far between, and getting rarer the longer she's here. Mostly, she "talks" to us all day long in widely-varied, squeaky meows and trills. She follows me around unceasingly, and begs to be allowed to sleep on my lap. Yesterday she even started running and chasing her toy.
She's not a jumper, and rarely gets caught on the table or countertops. She doesn't make much effort to go outside, or other places she shouldn't. She doesn't beg or steal food. She's not the sharpest pencil in the box, but she's the sweetest.
However, Emerald has a Talent that, while admirable, could not exactly be described as social. Emerald is a yowler by night.
Emerald's yowls are long. Emerald's yowls are melodic. Emerald's yowls are heart-wrenching and pathetic. Emerald's yowls are unceasing. They sound like a doomed soul futilely bemoaning his life of sin. When they occur almost anywhere in the house, but most particularly when they occur right outside your door, they jerk you out of sleep and shatter any remaining somnolence into a million little irrecoverable pieces.
If Emerald's yowls could be translated, they would say, "BA-ROOOOOOOOOOO, I haven't seen a HUMAN in A WHOLE FOUR HOURS! I'm sure they've abandoned me! They don't love me anymore! Human! HUMAN!! MUST. HAVE. HUMAN!!!"
As soon as she sees a human, these yowls immediately disperse into relieved, happy trilling.
One morning, Emerald sat outside my housemate's room and yowled for a solid hour. My housemates don't particularly need to be subject to that, especially the ones who get up in the morning for real jobs.
So I decided she'd have to spend her nights in the bathroom. It's heartbreaking, because she really doesn't like it, and there's a bit of disgruntled protest when bedtime comes and she gets carted off to her little dungeon.
However, it saves our sleep and our sanity, and despite her not enjoying it, it does have all the comforts of home: her bed, her food and water, and her potty. She survives quite well until the morning, when she is gratefully let out to resume her endless pursuit of cuddles.
In short, she's a delight, and I'd adopt her myself in a second if I could. She may be a nuisance, but she's a darn lovable one.
