Finally, all those photos you Instagram of your cat can do more than just elicit "aws" from followers.

Purina Pro Plan's My Great Cat campaign will donate one pound of cat food — up to 50,000 pounds — to feline rescue groups nationwide for each cat photo or video posted to social media with the hashtag #MyGreatCat.

The campaign, which runs through Aug. 31, launched on June 14 with a pop-up photo gallery in San Francisco, featuring the work of 19-year-old pet photographer Jessica Trinh.

Although Trinh specializes in dog portraits, Purina Pro Plan arranged for her to visit 10 cat owners so she could uncover what makes cats such incredible pets and capture their personalities in photographs.

"Having always been a dog person, I was quite surprised by what I found," Trinh said in a news release. "The playfulness, the authority they conveyed — and the love they clearly communicated. Each cat had its own story to tell, and I look forward to discovering more in my future work."

To inspire cat owners to recognize the greatness of their own cats, Purina Pro Plan is encouraging them to post cat photos using the #MyGreatCat hashtag.

Each picture posted contributes a pound of cat food, which will be distributed to hundreds of cat rescue groups through Rally to Rescue, a network that's saved more than 600,000 pets.
