The history of pet food
A long time ago, cats and dogs didn't have special food like they do today. Cats were hunters. They caught mice, birds, and other small animals to eat. Dogs ate whatever was left over from their owners' meals. ¹
In the 1860s, things began to change. A man named James Spratt noticed that dogs near a ship were eating hard biscuits. ² So, he created the first dog food. It was a biscuit made from meat, grains, and vegetables. This was a big idea! Soon, more people started making dog food. They added more ingredients to make it more nutritious.
³ They knew that cats needed meat and fish, so they made cat food with these ingredients. Over the years, scientists and pet food companies learned more about what cats and dogs need to stay healthy. Today, there are many different kinds of cat and dog food. ⁴ There are even special foods for pets with health problems.
Now, cats and dogs can live longer and healthier lives because of the good food we give them.
A. Some are dry, and some are wet.
B. But this was not very healthy for them.
C. Later, people also started making food for cats.
D. Pet food is a good choice for some lazy pet owners.
E. He thought he could make something better for them.
