My oldest male is over 2500g he is 16 or 17 years old. He has lost a bit of weight. I try to feed him every week. But he doesnt eat every week. He will eat 2 times a month then he takes a few months off. The he will start again take a few meals then off again. Has anyone else noticed that their older balls. 10+ years old their eating seems to slow down. I feed all my balls every week. So its not that he isnt getting offered food. He has beed to the vet everything checked out good. When he was younger he would eat everything thrown at him. Every week never even stopped eating while breeding. I just checked and all my males other than the 07's are over 1500g. Some not much over. The rest of my males are no older than 03's
