When a rabbit produces excess soft stool (cecals), the first thing to do is to examine its diet. A diet high in protein is usually the cause of excess cecals (barring any health problems).
What kind of pellets is Luli eating? Is it alfalfa-based pellets? Are you feeding Luli alfalfa hay as well?
Generally, it is recommended to feed baby rabbits with alfalfa-based pellets and alfalfa hay, as alfalfa is high in protein and a baby rabbit needs protein for growth and to strengthen its bones.
But some baby rabbits are sensitive to too much protein. In this case, you can replace alfalfa hay with timothy hay and see if there's improvements (hay is the most important part of a rabbit's diet and the fiber in hay helps to ensure a healthy digestive system).
If after switching to timothy hay, Luli still has excess cecals, cut down on alfalfa based pellets and switch him over to timothy based pellets slowly (i.e. if now he is eating 100% alfalfa pellets, give him 75% alfalfa and 25% timothy pellets, and slowly increase timothy pellets while decreasing alfalfa pellets). Changes to a rabbit's diet must be done slowly to allow time for its digestive tract to adjust to the change.
Added on June 15, 2008, 8:02 pmto reduce the smell of pee, you can add a few teaspoons of sodium bicarbonate into Bambi's litter, i tried this before and it works (cheap too!

). I also tried recycled paper litter, can't remember the brand now, but pet safari sells it, it comes in a few different colours (grey, pink, blue), it works well too in reducing odour. And after their spay & neuter, their pee no longer smells

hmm sodium bicarbonate.. that's baking soda right? will try some later, she just loves sitting on the comot
actually the odour doesn't really bother me cause it's only when i wake up in the morning.. ughh smelly.. then bring her outside then no more smell anymore. so i only need to tahan in the morning lol.
