Grumpy Cat, aka Tardar Sauce, has become quite the business cat. With a Grumpuccino line of drinks, a photo bomb app, odor eliminator, and commercials for Friskies, she’s proving that being grumpy can bring joy to others. Now you can make your weather more fun with Weather Kitty, an app that lets you customize your theme, including Grumpy Cat!

The app is free and gives a detailed 7-day forecast for your area. The fun starts when you unlock extra themes for $1.99 each. Those themes include Holiday Kitties, Fall Colors, Winter Wonder, Lil Bub, Halloween, Yoga Cats, Cats & Dogs, and Summer Fun (a free theme). Because I wanted the full app experience, I downloaded the Grumpy Cat theme and the Add Your Own Kitty Theme.

The Grumpy Cat theme gives a number of different photos and sayings, making your forecast much more interesting. For example, the last forecast I saw was “Your forecast: 100% chance of failure.” You can check out other apps and items relating to Grumpy Cat on her Web site.

You’re also given a number of options for your own pet, selecting a different photo for specific types of weather.

Are you ready to make your weather more interesting?
