What is it?

I saw this today, on the table.

I sniffed it.
I pawed at it.
I batted it across the table.
I walked over to it and pawed it again.
I batted it back across the table.
I pounced on it.
It didn't move or respond in any way.

I don't think it's alive.
I don't know what it is.
Weird thing.
