Using the Living World Small Animal Mineral Block is easy. Just place it in your pet's cage, and they'll naturally start gnawing on it. Remember to choose the appropriate size according to your pet's needs. The 40 g block is great for smaller animals or if you want to offer a change in flavor often, while the 190 g block is suitable for larger small animals or for a longer - lasting supply. Keep an eye on the block as your pet uses it. If it gets too small or dirty, replace it with a new one. Also, make sure your pet has access to fresh water at all times while using the mineral block. Store the unused blocks in a cool, dry place to maintain their freshness and flavor.
