Startup Idea : Pet Feeder

I know that automatic pet feeders are on the market, but i want to innovate it, i want to implement a web cam that communicates with a web page. The pet feeder can interact with an smartphone, to choose how many grams of food, and lts of water you want to give to you pet, in the app, you can administrate how you want to feed your pet, the app will also tell you when the supply of food and water will be over. The app can also contain information like pet database of food, veterinary, database of people that walk the dog etc...
