I've been researching what to keep my isopods on, and I've come across a formula (I think it originated on here) of organic compost, leaf litter and soaked wood pellets. The pellets used in the example are hardwood fuel pellets but I'm wondering if horse bedding pellets would work. They will contain softwood but apparently a lot of isopods prefer softwood and it is safe as long as it is not fresh and sappy. Or even wood cat litter pellets. Any thoughts?
