To create a ratio bar to represent the number of cats and dogs, you can use a colon (:). The number of cats is usually written first, followed by the number of dogs. In this case, the ratio of cats to dogs would be written as:

5 cats : 4 dogs

This ratio bar shows that there are 5 cats for every 4 dogs.
