But running round the bedroom floor must soon become boring to an inquisitive little rodent like a hamster, and also brings the risk that your pet will escape under piece of furniture that you can't move, or - worse still - under the floorboards!
So, why not combine play with exercise - hamsters like nothing better than a really good work-out!
You can buy a wide range of ready-made exercise toys for hamsters including wheels, see-saws, houses, slides and tunnels. Many of the new multi-level homes have tunnels, tubes and add-on rooms to provide extra exercise areas.
But with a little ingenuity you can construct your own exciting and ever-changing fantasy hamster gym - outside its everyday home - from bits and pieces you can find around the house. It's also a fun idea for children.
Here's what to do...
Put all of your hamster gym equipment inside the large florist's box - you can glue the pieces to the base if you wish. You can also add some manufactured toys if you like.
These are just a few ideas to get you started. You will have to replace the homemade pieces from time to time as they become chewed, shredded or 'played out'. Manufactured toys are built to last longer, but many hamsters will still destroy them, given long enough!
Remember that your hamster will probably think that exercise equipment is for eating as well as working out! Ensure that there are no staples or sharp edges in your gym, and do not use newspaper, in case your hamster swallows the ink.
You should also consider safety when buying toys for your hamster. Once again, avoid any with sharp edges, or openings which plump hamsters could get stuck in. Also, if your hamster chews a toy so that pieces snap off, file any rough edges smooth, and remove any small pieces completely. If you are in any doubt as to whether a toy is safe, throw it away.
