There's a mouse in the house

Have noticed the occasional sign of a mouse around and there are a few baits in Flynn proof areas to try and knock it out.
Recently found a nibbled on chocolate bar in the pantry and decided to put a bait down in there.

It must have worked as when Sandra came up to the kitchen the other day, she saw Flynn wondering if the thing he had found on the floor was edible......yes, it was a dead mouse.
No, he didn't get it in his mouth
