Hi! I just got my very first guinea pig ever a week ago, his previous owner was moving and was unable to rehome him so I agreed to take him in. I know next to nothing but have been doing lots of research on the internet. Ted is a 2.5 year old male. I had him out of his cage for some roaming around time and when he was walking I noticed one of his back feet had a bright pink spot. Is this normal? I tried to take a pic of it. He lives in one of those store-bought cages thats a plastic tub on the bottom and metal wire top. I cover the bottom with wood chip bedding. Thanks for any help you can offer!
