R.I.P. (again)

While working in another room I heard Persey, the Twink playing with one of his toys. He had spent most of the morning wrestling a black and white plush toy. This is what I thought he had started whacking round again later on. I went in to check and there was a dead vole (as blipped outdoors ) he treated it just as one of his several toys.
I have no idea how long it has been dead in the house or which cat to blame for it.
 Only in the past two days have we had rain and the voles' favourite bog has filled again. The cats like to hunt there.
Disgusting cats.
The rodent was laid out on paper & buried with full honours. A red Monarda (Bee Balm) flower placed by it's grave.
