Can I Compost Cat waste and litter?(From the Pet bedding & other waste category | 1 comment - join the conversation)
No, you shouldn’t compost cat waste or cat litter.
As meat (and random stuff) eaters, cats’ faeces contain all sorts of nasty bugs and dangerous organisms that you don’t want mixed in with your compost – particularly if you’re going to be using it on your veg bed. Although it’s tempting to add wood-based or paper-based litters to the heap (since they do break down quickly), it’s best to avoid anything that has come into contact with that potentially problematic poop.
(Wee is not such a problem – healthy urine is typical sterile – but the clumped litter might have come into contact with faeces at some point.)
If you’d rather not send it to landfill and have the space, you may want to explore a dedicated pet poo bin: dug into the ground and treated regularly with proprietary product (some are harsh chemicals, some are kinder to the environment), they break down poo quickly and without stinking up the place. Make sure you pick a litter that is 100% natural material/biodegradable, and any litter tray liners are biodegradable too so that they will break down along with the poo.
