They can but it's not a really good item, can cause very runny stools. Greens like turnip, mustard, collard, kale , endive, dandelion, and veggies like squash, green beans + peas are all better choices. A few blueberries + strawberries for fruit.
Mirage came out of brumation on April 26. He was doing great. On May 2 he started acting funny. We just redid his tank, and he keeps going into one of his hides. He just lays there. He shows no intrest in food. HELP!
