Can a mouse run so fast that you its like blur when see it?

Yes, a mouse can run so fast that it appears like a blur when you see it. Mice are known for their quick movements, and some species, like the house mouse (Mus musculus), can reach speeds of up to 12 miles per hour (19 kilometers per hour) over short distances.

At this speed, a mouse can cover a distance of about 19 inches (48 centimeters) in a second. This may not seem very fast to us, but when you consider the mouse's small size, it's quite impressive.

To put it in perspective, a house mouse is about 3 to 4 inches (7 to 10 centimeters) long, so it can travel a distance equal to its entire body length in just a fraction of a second.

When you combine this speed with their small size and erratic movements, it's no wonder that mice can sometimes appear like a blur when you see them scurrying around.
