Hello fellow gardeners ...
I am finally going to get a rabbit(s) after pondering it for some time. I think I found some good bedding/litter that is compostable. My question: what about the urine? does it burn plants or can it just be added into the garden along with the pellets and bedding?
thanks alot for your info. I will post a picture when I bring my new pet home!

dump it all into the compost. It super charges it. Don't use clay litter, is all. I use shredded newspaper, of when I've got more money than time, the compressed newspaper commerical litter. (looks a lot like the alphalpha pellets!)

if you pour urine directly on plants, yes, it will burn it - but that's because it's high in nitrogen. Urine diluted 10 to 1 with water is a perfect fertilizer. So in the compost, after time, and rain...no problems!

I use pine chip litter and it goes straight from the cage to the garden no problems. The dropping/litter worker really well in a Lasagna style garden with leaves, etc.

I think the urine volatilizes off pretty quickly. Earthworms are more sensitive to acid than are most plants, and red wigglers are raised under rabbits. The worms avoid any heavily-soaked urine spots until they dry out, but otherwise don't seem to have problems with the urine content.

I've used both rabbit cocopuffs and goatberries straight on garden plants with absolutely no problems. I usually do let them dry out before applying to potted plants, however.

I use hay under the rabbits, it doesn't go into the cage itself. They are on the porch of the garden/workshop shed, sheltered on the north side and shaded from summer heat.
I just scoop the hay and manure with a shovel and put it in the garden as mulch. I have never had any problems. The hay soaks up most of the urine and it breaks down slowly and adds to the soil.
