Baby CottonTails Found -- Houston

Question
We live in the country. Our kitty has been finding baby rabbits and bringing them into the house.  They look like cotton tails.  Are there any people that would foster cotton tails, as opposed to pet rabbits.  Please help before the little guys die of shock.  I'm in the Houston, TX, area.  We are giving the rabbits milk replacer.  There are 2 of them.  They are about the size of a man's thumb. The cat has been locked inside the house since she brought the bunnies home.  

Answer
A wildlife rescue would be your best bet. You can contact the local Fish and Game, and they can probably get you hooked up with someone. Definitely keep them fed with the milk replacer. From your description, they sound far too young to be without milk. I am not entirely sure how often cottontails feed their young, as they are in an entirely different genus than domestic rabbits, but domestic rabbits feed once to twice a day, letting the babies fill up pretty well.
