In one sentence, describe what the following article is about:

This will be your hamster’s bed. It will spend a lot of time hiding in the material as well. Make sure to pick up nesting material from your local pet store if you don’t have some already. Do not give your hamster material that separates into thin strands, like cotton or wool. The hamster can get trapped or choke on these materials. The nesting should be evenly spread across the doll house and the layer should be 1 inch (2.5 cm) thick. Now that the grunt work is mostly done, it’s time to have some fun with your hamster’s new home! Put together a room with an exercise wheel and some small furniture, like a couch and chairs, surrounding it. Place chairs on every floor of the house to give your hamster different spots to sit and rest. You can also add small lamps and bookshelves to make the cage look more like a home. You can get this tiny furniture at your local pet store. Make sure your hamster can get to each room by itself. Most doll houses have staircases, which work perfectly. Keep the food and water bowl next to each other and in their own separate area. This way, your hamster knows exactly where to go every time it feels hungry or thirsty. Most converted doll houses have the food and water bowl on the bottom floor of the house to make it easy for the hamster to access these things. Keep the food and water bowl in the room next to the bedroom. When your hamster wakes up, all it has to do is walk into the next room to get its food and water. Keep some small plastic balls in the bedroom, kitchen, and all other rooms so that your hamster will always have something to play with nearby. Place tubes in each room for your hamster to run through and use for exercise. Don’t clog your hamster’s home with toys. Hamsters like to run around and get exercise, but they won’t be able to do this if toys are taking up too much floor space . Make sure your hamster isn’t exposed to damp conditions or a room where people continually turn the lights on and off during the day. Hamsters are very sensitive to sunlight, so make sure their home isn’t exposed to bright lights. Hamsters are also sensitive to high frequency sounds and are easily stressed by them. Make sure your hamster is housed away from computer screens, televisions, and sources of running water.

Summary:
Spread nesting material across the floors of your doll house. Decorate each floor of the doll house with tiny furniture. Add a food and water bowl to one room of the house. Spread toys around the house so your hamster can play everywhere. Keep the cage in a dry, quiet part of your home.
