Big, green and brown puss moth caterpillar

I saw this huge caterpillar as it crept down the street. I rarely see such a large caterpillar. And this one had an unusual green-brown dress, and some kind of antennae on the back. For a moment I thought it was a snail, but it was a caterpillar. If I recognized it correctly, it is a brown puss moth caterpillar.

A bit like a space creature. Isn't it? ;)

This is what the puss moth looks like. A real dandy.
