Peanut & Butter - 2 day old foster kittens

I knew right away these were not going to be easy kittens to foster. There would be some sleep lost at the beginning, but I knew it was so worth it. These two arrived at the shelter at only a day old.  So tiny and so fragile!    
I hate to admit it, but the smaller and fragile they are, the more I seem to love fostering them.  I think I have the best volunteer job in the world.
