4 lb Channel Cat - Secret-7

Lately I've used treble hooks with Magic bait on bottom - with Secret-7 on top. Small catfish eat off the Secret-7 but I like 'bigger bait' and mixing the two makes a 'bigger looking Secret-7 bait i.e. Magic bait is just 'filler cause it stays on hook better'
I presoak catfish food and / or dry dog food to use as chum - and sometimes I'm not sure it's working - but when I cut open this catfish belly it was full of the chum I use i.e. I know the chum was working today (sometimes I think the chum attracts to many small catfish but today it got this 4 lb catfish to hang around for me to catch

Addendum: I forgot to mention I make a 'ball' of the presoaked chum - about the size of a softball i.e. use large ball of chum to hold fish in area
