Kirby loves fish and seafood so much sometimes we wonder if there is a cat in there under all that fur! He'll eat any type of fish, gobbles down shrimp, and will patiently wait for his bites of steamed, butter dipped crab leg meat when we are eating. Sometimes I mix salmon or sardines into his nightly meals.
I often dehydrate different fish fillets such as Tilapia, whitefish, and flounder. The easiest I have found is Tilapia which I purchase in individually packaged deboned fillets Make sure there are no bones to choke on and make sure the fish is thoroughly cooked. Try to choose fish with the lowest mercury which include Anchovies, Butterfish, Catfish, Crawfish/Crayfish, Flounder, Haddock, Hake, Herring, Mackerel, Perch, Pollock, Salmon, Sardines, Shad, Sole, Tilapia, Trout, Whitefish, and Whiting.
I don't even bother to let them thaw. I just place them in my dehydrator without any seasonings.
A few hours later I turn them over.
I check off and on until they are the desired dried consistency. Sometimes I'll cook them on the weekend, sometimes I cook them on a week night and end up letting them dehydrate over night. It's a chew so they really can't get too dry or tough.
The final step is Kirby's taste test. Kirby tested, Kirby approved!
