Hi all, I have two guinea pigs. The one that is hopping rather than walking(her names twix) is about 10 months old. I opened the cage for my guinea pigs to come out for free range time, and only my other pig (dizzy) came out. I thought maybe twix was just sleeping or something, but when I saw her she was awake just sitting in one spot. I gently picked her up and put her on the floor to have free range time, but rather than walking around she hopped. I was very worried and picked her up to inspect, and no poop was on the bum, she wasnt wet or messy, infact she looked completely normal, and her legs moved. I put her back on the ground and she hopped to the litter box but couldnt jump up (she attempted to) but gave up and peeded on the floor (which she NEVER does). I put her back in the cage and put food and water right near her so she wouldnt have to hop into litter boxes to get to it. All night she hasnt moved out of her spot, but i saw shes eating and drinking. When she attempted to get over a low litter box, her back legs dragged as she hopped over, thats why i put food and water close to her so she wouldnt do that anymore. I dont know whats wrong, please help!
