For all those big and small cat lovers out there, I have developed, along with app developer Keith Kolmos, my first wall paper app: Rick's Big Cats - for both the iPad and iPhone.

The app, which cost only 99 cents, contains 20 of my favorite pictures of lions, tigers, cheetahs, leopards, cougars, jaguars and serval cats - photographs that look wonderful on the iPad and iPhone.

I photographed the big cats in Africa, Belize and in wildlife parks throughout the United States.

Most of the big cats were photographed with my Canon 100-400mm IS lens. Click here to read about all my gear.

From within the app you can email a photo to your friends and even share it on Facebook and twitter - with cat lovers around the world.

I hope you enjoy the app. Click here to see all my app.
