Bed meeces?

I have been with my human for quite some time now.

I thought I was used to most things, but, last night, something strange happened... there were meeces under the covers, where my human sleeps.

I've never seen them before, but they kept moving underneath the covers, really quickly.

I pounced on three of them, but there was nothing between my paws when I lifted them up.

I looked at my human, but he didn't seem to have any answers.

It's so strange - I've never seen those bed meeces on my human's bed.

I was confused.

I had a nap.
