Hey, guys! My Little guy's doing great as you can tell from this photo. He's a healthy weight, spry, and very curious about his environment; I did notice he has some redness around his anus however and I'm wondering if this is something I should be worried about? Looks like it might be a little bit of blood, He's still being fed formula but I've been giving him a little bit of Timothy hay and I'm guessing that may be the issue? Any help would be awesome!
