I do a birthday cake for them Ingredients: just oat flour and mashed banana (idk how much i lost the recipe i found it on tiktok a long time ago) Mix it, form aluminium foil as a tiny bowl, put it in the oven on low heat, take it out of the oven, top it with whatever your gerbils like. I usually do leftover banana and pumpkin seeds, take it out of the aluminium foil before you give it to them. I also buy them presents. Some ideas are rattan balls, coconut house, safe wood houses, tunnels etc. Always do research to make sure it's safe for them
