After its giant cat calendar went viral last year, the Army Corps of Engineers’ Portland, Oregon, office is back with another one for 2024—and a version featuring giant dogs.

“This product was created to tell the story of our district and what we do in a way that is really enjoyable for the average public,” Portland district spokesperson Chris Gaylord told Stars and Stripes. 

The Army Corps of Engineers’ Portland office handles civil works in Oregon and southwestern Washington. The calendars feature giant dogs and cats superimposed over scenic photos featuring public infrastructure projects throughout the region. 

The corps operates in over 130 countries and supports soldiers by building and maintaining infrastructure and providing service members facilities to train, work and live in, according to the U.S. Army Corps of Engineers website. 

For the Portland branch, the calendar is about making engineering and the Army Corps of Engineers’ work accessible and fun. “Engineering is not that exciting,” Gaylord told TODAY.com when he discussed the inaugural calendar’s release. “We all believe that what we do is very important, and that’s the reason we don’t take our social media so seriously.”

The pets featured in the 2024 dog and cat calendars were sourced from 750 photographs submitted by employees of the branch, according to Stars and Stripes.

Last year’s cat calendar was downloaded over 530,000 times. “It was really so inspiring to see how much joy this little product brought to people all over the world,” Gaylord said.
