Having stool problems

Question
Hi my grand kids guinea pig i think is having troubles having bowel movements. For they are not little small pellets any longer it is like he is constipated and they are coming out in BIG clumps. Could you help figure out what he is missing in his diet.

THANK YOU

Answer
Hello, you could try a laxative or a piece of strawberry to help loosen stools. Do you give your guinea pig fresh veggies. A lot of times a half of cup or less of veggies a day is really beneficial and can help with constipation. What are you feeding him right now and do you give vitamin C everyday.
