I have have little gray mice bother my garden before, and they are confidently dealt next to with mousetraps. Lately, though, at hand is a slightly larger critter than runs very in a hurry across my patio, from one side to the other. I never see it running the three enclose walls like mice will. This critter is slightly larger than a mouse, and dismal in color. It moves massively fast, too prompt to get a suitable look at what it is! I'd say it's any dark brown or black. Any model what this is?
Answers:    it could be a vole...they can look like mice
