Where did you hear that oats don't mix for rabbits? Do you have any reference to this information? What type of fresh spring water are you talking about? Bottled water? Vets will suggest to rabbit owners if their rabbit has bladder sludge to use bottled water because it has a lower mineral content.Another poster suggested you feed your Mother rabbit 'Oats'. Do NOT do that. Rabbits and oats don't mix. They can harm your rabbits kidneys. Feed rabbits Timothy hay, Timothy pellets, dark leafy greens such as organic romaine or Spring mix, plenty of fresh bottled Spring water. You can give her treats of freshly washed carrot tops. And with new babies, make sure her environment is free of dust, excessive heat, flies, soiled towels. A fan is nice for her, just don't put it on high. Keep everything fresh and super clean. She also needs a great deal of peace and quiet. If your weather is warm, freeze a plastic water bottle so she can lay against it. Just make sure her pen stays dry.
