For panthers that age I feed daily - I offer them about a dozen crickets (or their equivalent in other insects, as I use silkworms, hornworms and wild caught grasshoppers and moths as well). Once the panther is a year old, you can cut down to feeding every other day - however I do continue to feed my females daily if they're being bred - but in that case I feed only 6 crickets a day (or their equivalent).
