Nice photos. Can you give some info about the shot, i.e. tripod, distance from subject (hopefully out of stones throw), lens, etc.

Rats are very intelligent. I've seen them use crude tools to get at food.
But I've never seen that before! Amazing ...and nice shots!

I assume it was wanting the stones to either cover something or support something. Would be fascinating to find out what it was up to.

Yes they are very intelligent and they bite!!!
Personally I cant stand the smell of rats and mice (comes from working with them in the labs) so I dont really like them but they are not dirty creatures except when they live in dirty places.

I think I have the answer to this:

From the way the rat is holding the stones, I'd say it thinks it's moving babies around.

Great find Eric.

I did some searching and found these critters sometimes do use stones for making nests. Also, it seems some species of these gather up objects and on the way to where they want to use them, they find something they like better and switch out objects and forget about the first item they had.
