Hi, so since I've gotten my piggies almost a month ago I've been trying to switch them over to oxbow but they really seem to like the other pellets better. They don't eat the Oxbow as much as they just pee on it. When I put both in my hand they will only eat the other pellets. I know that the old pellets are Timothy based there is 1200mg of vitamin C, and 0.8% calcium. Their old food is cheaper for me since Oxbow is a foreign brand it costs more. But I'm not sure what I should do. I added a picture but it's all in Japanese so I'm not sure how much help it will be. If you have any questions that would be more help then I would be happy to answer them.
