Is Tips a werecat?

My cat Tips has switched from her usual routine of howling at 2 a.m. - now she howls at 5 a.m., giving us an early wake up call (hey, I'm a writer, I don't do mornings).

Apparently, the 13-year-old Tips isn't a banshee in disguise. Her uncannily human-sounding wails are attributed to failing kidneys, making her thirsty in the middle of the night (or just before dawn).

Of course, she can't just go to her dish and drink. She wakes up the whole household instead. Maybe she's complaining about the switch from Wiskas to vet-recommended dry food. I'm too tired to tell.
