But souped up with minerals & vitamins. What I do is use stringer clips and place one 3/0 hook facing out on the clip add a cube with a center hole and another hook facing the other way. I use em on limb lines with the cube just a few inches under water. Good for Cat, Carp and occasionally most anything--had a sunfish snag on one once. A different way preferred by some is to have the hooks on separate lines from the cube and tie (or use a rubber band) the hooks to the outside of the cube.
How soft do those range cubes get once they're wet? And how long does it take. It seems to me that if the cubes stay hard a long time, they would interfere with the hook being able to do its job. If they soften up pretty quick, just keep a few wet so they'll go on the hook easily.
I posted a complete bait formula in the Carp Fishing section a couple months back with instructions on how I mix and use the range cubes (pellets) for cats and carp. Not sure how to link it to this message, but it is listed under new to carp fishing post in that the Carp Fishing Section, carp n' cat bait and rig . It works really well, easy to make and very economical. It will also last through the winter if you keep it refrigerated and works just as well next season. It is a great bait in warm weather for eater sized cats.
