Have we come full circle again, back to cats in the aquarium?

What about hair? You can get bags of it at a barber shop. It is 100% protein, and is resistant to bacterial breakdown, but not entirely. Suppose you had a soil-hair mix with plants rooted in it. Would it not be possible that bacteria could slowly decompose the keratin and release NH4 that could be taken up by the roots. It is worth a try!
