i had the same problem with my diamond yearling, so not impossible at all, i gave her a weaner rat and she took it no probs, nearly a week later she regurgitated the skin and fur... i saw this happen so not my imagination, i tried her with a smaller rat a week later and it stayed down... so i figured her food was to big... have had no probs since.
