I got a fussy eater and even though he is six months old, he only weighs 121 grams. When he has eaten, it has been live mice only. Due to several factors, his last meal was February 11th and even though I only have had him for five days, I noticed cruising/hunting behavior last night so I gave him a live rat fuzzy today and perfect strike and no delay in eating!! I am hoping next week to give him another live and then maybe see about f/t. Your post is extremely helpful!
