My guinea pig, named rio seems to be bleeding and i know it is not from any injury on the outside of her body. I picked her up to put her back in her cage earlier today and my hand which was supporting her butt had blood all on it. I've noticed she makes quiet high pitched noises and from what i've googled it seems as she might have a UTI, i heard her making the squeaking noise so i went over to see if she had peed and to check is there was still blood in it but it was some stool which i picked up with a kleenex and seemed to also have a bit of blood on it, does this mean it may be something other than a UTI or does the slightly bloody stool not change anything, she has been acting normal like nothing is wrong the only thing i've noticed is the squeaks and the blood. i'm bringing her to a vet tomorrow but i've been very concerned and wanted to see if i could get any advice from other guinea pig owners, thank you to anyone who takes the time to read this and tries to help i appreciate it greatly
