I have noticed my chinchillas poop seems kinda soft since I have switched over to oxbow in September does anyone else have this problem with oxbow food? My youngest chin Casper came to me sick with we thought it was girdia at first but we got him tested and out ruled that he's was on oxbow before we got him and the vet sed to keep him on it that it's the best but now after 2months of switching my other 2 to oxbow it appers that the food is the cause Of the mushy poop becuse we don't feed treats and they alwas have fresh hay and water ! any thoughts on this has any one else experienced this ?
