I just got myself a male pastel. I don't know what he weighed when I first bought him or a week later before his first feeding but I weighed him at 209g six days later (may 22) before his second feeding. I am feeding him f/t adult mice. On may 22, he was 209g. His next feeding was on 5/27 and he was 222g. It was a good 13g gain in 5 days. His next feeding was on June 1 and he had only gained 7 more grams. I wasn't able to feed him again until today (June 8) and this time he's only gained 5 grams. I've noticed he poops a lot. He didn't use the bathroom within the time period of the 13g gain. But he used the bathroom between both of the next 2 feeding periods. As I said, he's eating f/t adult mice. At 234g should I step up to small rats or stick with the adult mice? Small rats look a little too big to me which is why I was sticking to the mice. But my main question is whether or not his weight gain is bad or not. Should he be gaining more weight? Any suggestions or advice would be greatly appreciated. Thank you all very much!
