Alex, I to have carpet sharks that are very particular as to the treats they prefer. I've found that they go abosolutely nuts over Tender Vittles cat food. I tried a Tender Vittles vs. raisin experiment once and they only ate the raisins after they were sure there were no more Vittles to be had. I would think that Tender Vittles would be good for them at least as a treat. They have 24% protein, vitamins and minerals including taurine and poultry by-product meal as the first ingredient (After water sufficient for processing). I would never recommend feeding it for the main diet. Maybe Dr. Williams or one of you "Nutrition Experts" out there could take a look at TV and let me know any down side of TV as a treat alternative to raisins and the other common stuff. And finally to the person that said: >Only humans seem to override the signals sent them by their bodies >regarding nature and extent of food intake. Apparently you have never seen a horse that has broken loose from their stall and found the feed bin. The result is colic and founder and usually requires destruction of the animal if it survives.
