Choose a pet that you like.

Find out how it lived in the wild. What did it eat, how did it get its food?

Now find out what you should feed the pet with. Can you see how the food you get from a pet shop is connected to what your pet would eat in the wild?

Now think how much running your pet might do in the wild. Can you see why, for example, big dogs need to be taken for regular long walks. (I have a dalmatian: it needs a good 3 miles walk a day, that is over an hour's walking a day. If I did not do this I would not be treating the dog well.)

(These long walks are good for you, too, because they burn off any overeating you may have done.)
