Guinea pig Walking problems

Question
Hi my guinea pig seems to have trouble walking. I'm not sure what happened but one of her feet in the back is completely black compared to the other one, which is white. She has a lot of trouble walking and seems to be trying to push herself to walk. Everytime I see her she is always in the cushion that we gave them to sleep in. I'm getting worried that she broke her foot and can't eat anymore. Please help.

Answer
Hello Paul,
if the foot is turning black it's possible it could be broken or there may be poor circulation going on. I would certainly rush the guinea pig to a vet as soon as possible. You will need to try and hand feed her by using a feeding syringe and smashing up her food and adding warm water or pedialyte and feed it to her until you can take her to a vet.
