I use the Tractor Supply food also and have found the cats and everything else love it. Even have had some bass this year come up for it. I was spending 10.00 a pound on my Koi food and now they get the catfish feed also and are doing great. As far as the blues I have never caught one on the trotline or rod and reel on cut bait but live shiners that's a different story. The 116 pound blue caught here in the Tennessee River in Alabama hit a live skipjack herring about 18 inches in length. I was caught in the lagoon for the local Nuclear Power Plant so maybe that had something to do with it!
