I am relatively new to rabbits and need a little advice, please. Miss Bun always has packed poo on her butt. I do not see her eating her cecal (spelling?) droppings anymore, either. She gets Oxbow Timothy hay, about 1/8 cup of pellets a day - mix of Purina Show Chow and a good pellet that is not alfalfa based, as I thought maybe the Show chow was too rich. She gets a little piece of kale in the morning, an occasional baby carrot, an occasional alfalfa chew, and two yogurt covered timothy hay treats at night. Someone had said oats would help, I have tried adding a little bit to her pellets, no luck. Any ideas? Thanks!
