this is the way i cure my livers whether they are beef,chicken, or pork. cut them into bait sized pieces with old scissors. them coat the livers with garlic salt/pepper seasoning you can buy it at any dollar store usually. put them in an old tray or something for several hours in the sun. then flip over and repeat the process until both sides are tough. it will also help attract the cats if you save the blood to put back in there after you finished cooking em. its one easy way to catch decent sized cats.
