Does anyone know a website in which you can view Americas favorite pets? I need it ASAP, please.

You could try this:

Go to http://www.google.com and click on Images.

Type in america's favorite pets and see what happens.

Dogs and cats will come out on top, but I don't know the numbers. If you also want to know data, you can conduct the same search without clicking on the Images tab first.
