Your small pet, like a hamster, gerbil or rabbit, might seem to always be active (especially in the nighttime hours), but that doesn’t mean they don’t need some encouragement to exercise.
You can take your rabbit, ferret or other larger small breed animal for a walk on a leash, or provide time for him to move about outside his cage in a safe environment. Rabbits like to hop around in soft grass, so provide an enclosure for them to do so. A harness made for rabbits or other small animals can allow you to take them on a walk as well. (They don’t need to go far.) Just be mindful of keeping your small pet on a softer surface and out of harm’s way.
For your small pet that lives in a cage, like a hamster, gerbil or mouse, provide lots of tunnels that extend beyond the confines of the cage. Your pet will like to climb, explore and run. A running wheel in the main cage is also great exercise, and it will provide hours of movement and entertainment for your small pet.
