My guinea pig (she Is 1 one year old) has a little ball, a little bigger than a cherry by her anus. She has had it for a couple of days and it doesn't get bigger nor smaller. She is eating and acting normal. Even popcorning. It doesn't seem to bother her but I would like to know if it is dangerous.

It would be much more helpful if you could repost your question with a photo or photos. It is difficult to give advice without seeing it. It does not sound serious at this time but you should take her to the vet for an exam in the next week or so if it does not resolve. Any abnormal finding should be checked by your vet. I hope this helps. Feel free to repost with photos if you can.
