The hunky fraternity bros of Cornell University's College of Veterinary Medicine have stripped down to pose with their four-legged friends once again for their annual charity calendar.

Each year the dudes of Omega Tau Sigma round up their most adorable kittens, puppies, horses, cows (and strapping young friends) to grace the pages of the calendar, which benefits their fraternity as well as the Patient Assistance Fund, a local nonprofit that helps people in need pay for their pet's veterinary expenses.

And judging by their Instagram, the brand new 2016 calendar is going to be just as sexy as last year's.

Check out a few of the best shots from the 2016 Men of Vet School below, and pick up your own copy at Etsy.
