Moved into an older house and discovered a huge nest of mice under the sink in one of the bathrooms. With the cats gathered in a semi-circle to watch the show, we put on gloves and started cleaning them out.
Ugh. I'm not crazy about rodents, probably from too many years of viewing them only as food.
Anyway, suddenly a mouse made a run for it across the floor. As it happened, my cat, Roger the Lodger was yawning at the very same moment.
The mouse literally ran into the Roger's mouth. It was embarrassing to watch the cat - Puh-Tooie! - spit the mouse out and then paw at his face as though grossed out by getting mouse cooties in his mouth.
OTOH, he would sit at the window and twitch, shake his tail and chatter his teeth over the bird traffic which was safely on the other side of the glass.
I think some cats just aren't the vicious killers they're supposed to be.
