Why is my 2-month-old guinea pig bleeding when peeing or pooping?

My baby guinea pig (female) about 2 months is peeing or pooping and blood is coming out. Could this be because I’m feeding her adult food and I just realized it? What’s wrong with her?

Thanks for using Petco Pet Education Center, formerly Petcoach! This is not likely to be because of the food you are feeding her. This is though very concerning. This may be because of an inflammatory or infectious condition, among many other possibilities. For this reason, I recommend that you have Beaver evaluated by a veterinarian as soon as possible so that they can proceed with an exam, gathering more information and deciding what would be best for Beaver at this point. I hope they can help her!
