I've used fullers earth cat litter in the garden and it behaves like any

Hi Stuart,

Someone just sent me this link which may be of interest:

The good stuff is "Tesco Premium Cat Litter." Interesting discussion
about the cost of cat litter versus identical horticultural additive
(litter is 3 times cheaper).

Many thanks. Our cat is sadly no more, but I shall be off to Tesco asap :-)

The photo looks like gravel and I'll be interested to see what happens
to it when it has been wetted and then dried out again. I suppose the
clay ball type of growing media used in hydroponics might be similar?
I'll google the molar clay.

Although I'm a big vermiculite fan, I do wonder whether in winter it
maybe holds a little too much moisture. I use it 1:4 with general
purpose compost, but a little goes a long way.
