Got two guinea pigs, coco and snowy. I'm pretty sure they're around two. The past two years have not been the best for them. Previous owners were pretty neglectful and I followed. While I've been caring to them, giving appropriate food and letting them walk around in my room for a few hours a day, I've been neglecting the cage. Was getting cleaned every two months at some point and I'm relatively sure they're ill now. I do want to fix the mistakes and have started cleaning it alot more often, but their health still concerns me. both have slight black parts on the feet (doubt it's skin.) one has a lump as well. I do plan on going to a vet (or will atleast try convince my guardians) but I really don't know what to do afterwards.
