Hello, this is quite urgent, my young female guinea pig fell out of my hands when I picked her up out of her cage and is now acting very lethargic and breathing heavily. I tried to entice her using hay, but she can barely lift her body to reach it. She tries to get up, but tends to fall over and lay down after a few seconds. My dad does not get his next paycheck for 3 days, and I'm worried that her condition is severe and I don't want her to get worse. I would like some suggestions on how to care for her until we can take her to the vet, thank you.
