I have a 5-6 year old male intact Guinea pig that as of yesterday is pooping less. Still a decent amount but not the crazy amount like usual. No changes to foods or diet. Always has hay available no change in brand andhenever has had an issue with it before. He hasn’t eaten as much as usual of it recently but that’s not due to not having it available. Eating critical care well and his greens as well as most of his oxbow supplements. He has been getting a few more treats than usual but nothing new to his diet. What do you think is causing the lesser amount of poop? He is acting normal for his old little self and is currently chowing down on his parsley like no tomorrow!
