Offer her a variety of toys to play with. This could include things like chew toys, balls, tunnels, and hideouts.
Arrange her cage in a new and exciting way. Move around her toys and furniture to create a new environment for her to explore.
Give her some interactive toys that she can play with, such as a puzzle feeder or a treat ball.
Spend some extra time playing with her. This could include things like hand-feeding her treats, letting her run around on your bed, or taking her for a walk in a hamster ball.
Encourage her to explore her cage. Place treats or toys in different parts of the cage to encourage her to move around and explore.
Provide her with a variety of things to chew on, such as wooden blocks or apple sticks. This will help keep her teeth healthy and provide her with something to do.
Talk to her and interact with her. Even though she can't climb or use her wheel, she can still enjoy your company. Talk to her in a soothing voice and pet her gently.
Be patient. It may take some time for your hamster to adjust to her new circumstances. Be patient and understanding and she will eventually start to enjoy herself again.
