I was wondering if this is a decent brand or not. I got my boys a bag about two weeks ago, and am beginning to think they don't like it. Before that I bought them Oxbow Timothy hay. The Kaytee bag was the same price for double the amount of hay oxbow bags contain. I thought it would last longer. I have seen them chewing on it, but they throw it all over the cage floor! They didn't do that as often with the oxbow. Should I switch them back?
