When one takes an animal into their home one must expect it to act as animal.
Much as to the distress of people that allow another human that acts as an animal into their homes.
Cats are interesting, my two cats caught a mouse in the kitchen, getting ready for work we saw the cats batting the mouse from paw to paw. We watched as the cats soon got tired of the game and one picked up the mouse and carried it to their water bowl. Poor mouse paddled about trying to get out but every time it reached the side one of the cats would bat it back in. My cats were not hungry, just doing what cats do, playing with a potential food, or just for the heck of it.
Came home from work, first thing we did was look in the water bowl, no drowned mouse. Both cats in the window happy to see us, so where was the mouse ?
I had a small throw rug in front of the kitchen sink looking all pristine and found the Mouse under there. The cats had placed it there after they tortured it to death and had smothered out the rug so it was not to been seen.
Animals are just so, they live on instinct cannot expect them to act as human. On the other hand with the news today humans are acting more like animals and they are the ones we do not expect to become a danger to us.
