I have heared that its not the smell to us that makes chum work. They say its the protien and other chemicals in chum that makes cats come to it. They say what we smell is not the same as it is under water. What do you catman think about how chum works. Im thinking if it isnt the bad smell that makes it work than there are probaly some good chum recipes that dont smell bad to us. If its protien related maybe a meat base chum would work good. Just wondering what everyone thinks.
