I got goober from the store a month ago, he had been there a year! poor guy. Was caged with another ball. They said he was 1 1/2 yr old and ovealy small. I weighed him yesturday and he is 225grams. I'm just wondering what is a average weight for a ball this age? He is eating good for me know. They had him on small weaning mice, he just had his first adult mouce this week. He's happy and healthy I'm just curious about a healthy weight to ame for. Thank you!
