It was like living with a teenage rabbit again. I tried to put myself in her place, and gave her extra petting and attention to help her through the transition. As time went on, I noticed her rationing her pellets. Instead of gobbling them up in one sitting, she'd have a few left over at the end of the day. Whether she got wise to the new plan or her metabolism adjusted, I don't know.
Obesity can be a real problem in house rabbits.
They burn less energy living indoors, exercise less, live longer, and eat table scraps. Excess fat can press on the internal organs and affect their function. Some rabbits are so fat they can't reach their cecal pellets or clean themselves. They are at risk for diabetes, liver disease, and heart attacks. Any change in diet should be gradual.
