There are several ways to keep a pet hamster entertained and active in their enclosure. Here are a few ideas:

1. Provide a variety of toys and accessories such as a running wheel, tunnels, and chew toys. This will give your hamster different things to explore and play with.

2. Create an obstacle course with items that your hamster can climb over, crawl through, and run around. This will keep them active and engaged.

3. Hide treats around the enclosure, so your hamster has to search for them. This will encourage them to explore and use their senses.

4. Offer different types of bedding and nesting material such as paper, cardboard, or hay. This will encourage your hamster to burrow and create a cozy home.

5. Rotate and switch up their environment by moving their toys and accessories around. This will keep their living space fresh and new.

Remember, it's important to provide a safe and comfortable living space for your pet hamster. Always supervise them when they are outside their enclosure, and make sure they have access to fresh water and food at all times.
