Monster Cat Roundup


The Roundup is relatively new to the Montana Cats Circuit, it was started in 2009 by Montana Cats board of director Steve Harris. This tournament is held annually on the 3rd weekend of July on the beautiful Yellowstone River. Tournament headquarters are stationed out of the Sidney Bridge in Sidney, MT. Boundaries stretch from the Montana – North Dakota state line to Elk Island. The event is limited to the first 60-teams entered and it continues to fill up on an annual basis. The Roundup is unique in that it offers river-side weigh-ins and a sandy beach for every boat to rest comfortably before and after the competition. Steve, and his Wife Ashley, are the current tournament directors.
