Rat Project Logo Test

These are not for public/commercial/private use by anyone. The font itself, Lato, is a free font that you can use for commercial use freely (my new love). As the title says, it's just a logo test I did quickly and I'm going to use the first one until I get more time to play around with the logo (because there wasn't enough time for me to have fun in Illustrator). I don't think I'll use any graphic elements in the logo and will try to keep it clean, elegant and modern.

Tell me what you think and which you prefer. I may be messing with the last one later to try and turn it into a rat-like shape (make the "p" it's head and put a tail on the "t").
