rabbit droppings are the most benificial to plants of all the manures out there, and the safest .. i have had a large number of rabbits myself a few years ago and the next in line is chicken manure, but its very high in acid and is very good for tomatoes,.. but as said before rabbit is the safest and the has the most nutrients for all plants, and its very clean to handle, good for indoor potted plants, no smell and very clean and easy to use....its all proven by science..
