What's cuter than cats? Shirtless firefighters exercising with cats for a few good causes! The Australian Firefighters Calendar has been raising money for various charities for 25 years. Now, there are several calendars of shirtless firefighters posing with cats, dogs, and horses to choose from. The proceeds go to support charities including childhood cancer nonprofits, a group that works with people with Down Syndrome, and several animal organizations.
