Why did it make the rabbit sick? I often recommend Yesterdays News as rabbit litter and have never had a single owner have any problems with it.rot wrote:
I think yesterday news does clump but it made the rabbit sick
As to the bird seed as litter, I wouldn't expect it to clump or absorb well (we sometimes recommend unpopped popcorn as a temporary litter for owners to be able to collect a urine sample from their cat at home), but it can be used to make biochar if you have some that goes rancid or otherwise unusable. Biochar is a great supplement to compost or directly to the soil. Make sure you add it with a good nitrogen source or soak it in a nitrogen source such as urea or fish emulsion or it can "steal" nitrogen from your soil.
Be as green as you can when producing biochar - I make mine only when camping so I'm just using a fire that's already there, I don't build a fire just to produce the biochar. It is also best to make sure you are burning the off-gassing fumes so you aren't adding more emissions to the atmosphere. Search hmmmm, is it "Jason's retort"? You'll find it if you search "biochar". Slightly off topic, but the urine soaked Swheat could be turned into biochar also.
