Here's a unique way to help dogs without a home.

A company in Turkey has created boxes in which people in Istanbul can recycle bottles in exchange for food for our four-legged friends.

It's pretty simple: people toss out their bottles, at which point some food comes out for the pooches to enjoy. The hope is that recycling the bottles will help pay for the dog food.

It's a novel idea for Istanbul, where there are some 150,000 stray dogs and cats. Who knows -- maybe it will catch on stateside.
