Sarchasm, My cats had been about 6 to 8 months when I put the bass in. At that time they were 10 to 11 inches long and chasing schools of fat heads across the water. I put in 50 crappie minnow size F1's; about 1 to 2 inches. I have no reason to believe that over 25% of them survived. I'd wait a little longer and put in some 6 to 8 inch bass. Essentially everything in the water eats everything it can catch and get in its mouth.
