Help!! My cat got a baby cottontail

[PastelToro]

I heard a baby cottontail screaming outside so I ran to go and grab it from my cats mouth, I've had her since last night and she is still breathing and alive. She hasn't moved since I got her.. I put her in my room in a tank with orchato grass Timothy hay pellets and shavings... She looks old enough to eat on her own but I'm not certain.. she probably has internal injury... I don't know what to do.. all wildlife centers near me will just put down the rabbit and my mum won't pay for a vet or drive me to a wildlife centers that will avtuactu help her.. please help here's a picture of gerher hi

She's lost the white strip on her head and is most certainly old enough to be on its own the best thing you can do for this baby is to find a safe release area...cottontails stress really bad in captivity so your unlikely going to be able to get it to eat or drink...hope this helps I used to be a vet tech and animal rehabber
