alternative to rock salt

[alanvendy]

i've heard cat litter can be used instead of rock salt. i have 2 posssible theories on how it works :-
1 it simply adds more grip to the slippy stuff.

2 it encourages all the local cats to p##s on it so melting the slippy stuff.

if you have any more ideas please comment.

The real reason is it absorbs liquid so dries the surface.

also it creates a grippy surface eh, dont think it melts the ice just puts a roughness on the surface, small chippings or coarse sand will have the same effect

ASdas are buying tonnes of UREA to spread on the roads and car parks. I take the P#ss when I see the yard boys up to their elbows in basically P#ss. bnut this joke goes over their heads.
