My girls like catfish when filleted and cubed into small chicken nugget sized pieces, then pan fried in olive oil.
To coat catfish (and bluegill fillets) I use three bowls and coat in the following order after rinsing and patting dry:
Bowl 1: flour + pepper
Bowl 2: 2 beaten eggs with a dash of cold water
Bowl 3: Italian (or Panko) breadcrumbs with a bunch of seasoning (more pepper, garlic, garlic salt, and whatever you like)
Pan fry until golden. Put out bowls of your favorite dipping sauce out. Simple and they like it. I still don't care for the texture.
I also noticed the cleaner the water the better tasting the cats.
