I have a little guinea pig that is almost an year old. Today she was really excited by her food and squirmed out of my hands to run towards the food when I picked her up. At that moment I was standing near the balcony door and I think she fell on the ridges at the floor that are there for a window to let it open and close. I checked her body for any weird bumps but she seemed fine. She din't squeek either when I gently pressed against her body to check if it hurts. She has normal breathing as well and is walking and running around like normal. She is also eating and drinking her food and water. I can't take her to a vet since in my country there are no proper vets for exotic animals like her. I'm really worried about her, can someone tell me what to do?
