Ever since I’ve had Sunny (4 yrs), I’ve used the pine pellets sold as horse bedding. It’s always either been  Equine Fresh or Tractor Supply’s brand . That’s all I’ve ever known. Well now, I’ve moved across the country and can’t find those anywhere over here. I went to three different farm supply stores yesterday. All of the pine pellets for horse bedding contain zeolites….not really sure what that’s all about but I did a quick search while I was at the store on my phone and came to the quick conclusion that I shouldn’t use those. Am I correct? Or is that ok to use? I also looked for what I’ve seen on this forum, feline pine, and didn’t see it anywhere either. The only other thing I’ve seen are bags of wood fuel pellets and I’m a little nervous about those because I fear that maybe they have other things in them that they just don’t print on the bag. There was one store that had a particular brand that may be ok after I research it, but it’s called America’s Best. The bag says it is 100% Douglas Fir. Is Douglas Fir pellets ok to use? Has anyone else used these pellets? Just looking for some guidance here before I have to make a decision. Thanks!
