My male Childreni was rather hungry last night, it ate 4 30g rats in succession. My male Coastal ate 2x300g,female2x 250 and all4 maccies ate three fuzzies each with my yearling Childreni eating 4 pinkies. Just wait until your Syd is looking for food and give him another. If he's not looking for more offer it anyway as he may be conditioned not to expect another but will take it if offered. Good luck and let us know how you go with him
