Breeding Tip: Tame 1 Male & Female, level them only in food. These will be your starting breeders since without high food, jerboa babies die within 15 seconds of birth. One you have a baby born with high starting food, take it a mate and level that mate in health only, breed them until you have a baby with high starting health. Now tame a mate for that baby and level it only in weight, mate it with your Food & Health Jerboa to create your Main Breeding Pair and go for the ever popular mutated Cotton Candy Jerboa.
DO NOT believe that this reduces weight on its inventory. As of today AUG 2020 I tested stacks of meats and berries etc, IT DOESNT. But instead it increases spoil timer of foods, meats and berries on its inventory. ⬆️ to prevent ppl from false informations!
The weight reduction does work. However the actual numerical weight of the items don't change. When placed in its inventory the weight looks the same. But when you pick it up after placing heavy items in its inventory look to see how much weight your actually carrying when it's on your shoulders. I promise you'll be happy
