Hello, one of my Guinea pigs is having very light color dry crumbly poop. The three ladies live together and I noticed the distinction yesterday. I had to isolate them three for a few hours to find out who is having it. Dolores is the one getting it, she is one year old and was recently on antibiotics for a very mild upper respiratory infection (nose had slight discharge and she was hooting 15 days ago) vet gave her antibiotics for 10 days, which got over on 10th June. We recently noticed this colored poop. I m very concerned going to the vet again tomorrow. Wanted to get advice here, tonight i syringe fed her 5 ml of water. She is eating hay, veggies (50gms a day - 25gms lettuce, 10 gm red pepper, 15gm cucumber), some days I’ll alter cucumber with parsley, cilantro, carrot, cabbage, Brussels sprouts, broccoli) and some Oxbow Garden select pellets 1/8 cup. She does drink but maybe not enough ? Is the poop of concern ? Could it be side effects of antibiotics but she has been off of it for 3 days and is cleared for any discharge or hooting. The good dark colored poop is other piggies.
