GBtortoises said:Both ZooMed products have better fiber, protein percentages and calcium/phosphorus ratio than Mazuri does. The ZooMed products are hay based pellets. The nutrional information of these the products (and others) can be found on each of the companies websites. The general concensus is that most tortoise species diet should be high in fiber, low in protein with a calcium to phosphorus ratio of at least 2:1 or greater. Both the ZooMed products fit these parameters well.
