2 1/2 week old baby not eating or pooping

2 1/2 weeks ago my cat brought up a day old cottontail. I had no expectations of it living more than a day or two, but here we are at almost 3 weeks and she was doing good until a day or so ago. Her poop kept getting smaller and lighter in color and as of yesterday I haven't seen any at all. In the last day she has refused to eat more than 3/4 - 1 ml. If that much. She's limping on her front paw and making a weird noise when she moves her mouth. She still seems pretty active....trying to get out of the cage I have her in, moving around, etc. I'm just really worried about her. On top of that, a friend of my husband just brought 2 more 1-2 day old bunnies that his mother in law's dog brought up. I am in Mountain View, Arkansas if anyone knows anyone in my area with more expertise, I really need to get them to them.

Please help!!!

Can you try and do a google for wildlife rehab in your area? even in your state and perhaps you can phone for assistance?
Unfortunately wild baby bunnies do not fare well at all when raised by us.

Call your local vet's office or a few in a bigger city near you. I know ours allows you to surrender wildlife to them, and they do immediate vet care if it's needed, and then get the animals to a wildlife rescue/rehab. Here's one website that lists some....maybe there is a place near you? http://wildlife.rescueshelter.com/Arkansas
You can also try calling your local animal shelter to see if they have a resource. http://www.schspets.org/
We tried rehabing wild rabbits, after finding a nest of babies and a dead mother (she got run over by a tractor). Most of the babies died. The one that lived, we had to set free. They just don't do well, and they need someone with the expertise to take care of them.
