I have a 3 day old kitten who's breathing very hard, labored almost like she's sucking air. I took her to the emergency vet but they said it 3 days old there was nothing they could do. They gave me some formula and a syringe as well as a heating pad, the tell me she's most likely not going to make it. She has a very strong cry. In fact she hasn't stopped crying for about 4 hours or more. I'm so nervous feeding her with a syringe and causing her to aspirate. I ordered the miracle nipple from Amazon but they said it won't be here till Thursday. I don't know what else to do, I can't give up on her
