She wasn't born with this name. She EARNED it!
;-)
She had a sister we called "Killer". Killer would kill things, like mice, rats, birds, lizards, worms, etc. And Psycho would bring them into the house and play with them.
She's a Japanese Bobtail - and makes more noise than any Siamese I've ever owned.
She's sleeping now - but... good grief...
My Psycho did what your Killer does. Also he would run across the room and attack you without warning. One Christmas he took off and tried to run up the Christmas tree and knocked it down - twice. But, sadly he dashed in front of a car and was killed.
