I have a cat. And, I buy toy mice for the cat to play with. And these toy mice are very realistic looking. So, whenever I see one on the floor, I just ignore it.
Well, the other day, when I was vacuuming, I kept pushing one around with the vacuum. After a bit, I came to realize that it was really a dead mouse. So, I disposed of it.
I guess that I will have to be more observant.
