Can I add used cat litter to my compost heap having removed all solids first?



No - it isn't a wise move as there may still be eggs from the toxocara parasite in there. Definitely not recommended!

Also a lot of cat litters are treated so they soak up moisture and this dries up your soil.

Good answers above..I am a cat breeder...not a good idea to put used cat litter in your compost heap...unless you want all the neighbourhood cats using your compost heap as a litter tray. We may not be able to smell the amonia after a while but a cat can. pee kills plants more than dog pee so not a good idea. I have a litter disposal 'situation'. My solution is to remove solids ASAP with toilet tissue and flush down the toilet then spread the litter over soil in a specially chosen place in the garden where there is a lot of sunlight...the odour will almost disappear...and you can re-use the litter or, since the smell disappears, almost, you can just leave the litter there. Some litters look like little white pebbles so seems like a garden feature...maybe around a garden ornament or as a standing place for pots etc...decorate it with stones, mix it in with other small ornamental gravel..plenty of ways to dispose of it and re-use it.

We have 3 cts and only the baby one uses a tray occasionally. I would n't use cat litter in the garden because of the potential bacteria in there also, I fell it would be an invitation for our cts, and others to use our garden as a WC! We dispose of the cat litter in the household waste as recommended on the packet, I wouldn't put it in the compost heap as compost works better if it's clean and healthy.

All of the above plus most cat litters are kaolin or similar based. That is a mineral so wouldn't break down and would alter the chemical composition of your soil.
