Three top breweries have joined forces to help an animal sanctuary in Minnesota.

St. Louis, Mo.-based Perennial Artisan Ales, Side Project Brewing and Chicago, Ill.-based Off Color Brewing have collaborated on ProCATStination, a 6 percent ABV Belgian-style saison that has been aged in wine barrels, and brewed at Perennial Artisan Ales. The new beer is being brewed exclusively for Lions, Tigers and Bears, an annual fundraiser that benefits the Wildcat Sanctuary in Minnesota. The Fundraiser takes place on the second Friday in June at the Northdown Taproom in Chicago.

“TWS, a non-profit organization, is home to over 100 wild cats providing natural sanctuary and inspiring change to end the captive wildlife crisis,” reads the beer label. “With the generous support of the top breweries in the world, LTB offers the rarest, most unique, top-rated, and one-off kegs for great drinking for a great cause!”

According to filings with the Alcohol and Tobacco Tax and Trade Bureau (TTB), the new limited release will be packaged in 750ml bottles. Emails sent to the breweries for additional details were not returned.
