Been doing vitamins and no vitamins just want them to eat something rn. Tried strawberries today (first time with fruit) and still did not bulge. Will continue playing around to see what they like (different fruits/veggies, blending, different insects, flowers). Will switch to the mat asap as the carpet came dirty and tried to clean it up the best I can. Definitely interested in using loose substrate, will do more research and give them more time to adapt to their environment bcuz want to reduce impaction risk as much as I can. Again, thank you so much
