Chemicals dangerous to cats are phenols, ketones, and terpenes. Each of these is found in cedar oil.
My cats use the Yesterday's News (or similar brand) of newspaper litter. It's great, keeps the smell down, fairly light and doesn't ever track more than 3 feet from the boxes. It's awesome…and it's made from recycled newspapers and baking soda so it's totally biodegradable too. I love it and the kitties do too. The cedar stuff is better than clay…but remember, it takes a very very very long time for a cedar tree to grow (buying the wood whole is very expensive) so it's not necessarily better for the earth to turn it into cat litter instead of awesome trunks for blankets. ALSO, my brother and his gf bought it once and it had moth larvae in it (unbeknownst to them) and now they have a gazillion little silvery moths ALL over their house and they can't get rid of them. Watch out for that too. 🙁

I do not recommend formulating insect control solutions for the animal health industry from any kind of cedar oil other than ours. First of all, it probably will not work as it is low on the ingredients needed to kill or repel insects. Second, it will have certain components that could make an animal ill. It took me many years to formulate insect control grade cedar oil that could be used on cats and dogs. The aromatherapy grades will not work.There are are more sensitive to essential oils than dogs and humans. In addition to their hypersensitivity to smells, their metabolism isn’t as efficient at breaking down essential oils as dogs or humans so over time, toxicity build up is a true concern and can even be fatal. Moreover, the smell is just overpowering to them that it can literally alter you cat’s behavior. Cedar oil or products containing it (like Pine-Sol) should not be used around cats, even putting it on your dog is not advised, such is the cat’s sensitivity.CEDAR OIL IS AN ESSENTIAL OIL derived from the wood of conifers trees (trees that produce cones) like the Cedar. Cedar oil is very effective at driving away any number of insect pests such as fleas and ticks, mosquitoes and even scorpions and is great for use on both dogs and people…. It’s different with cats.If you're caring for feral cats, whether to use cedar chips as bedding is a matter of dispute. Some feel that cedar chips in bedding help repel fleas and are fine for general use in feral cat shelters. However, the national feral cat advocacy organization doesn't advise using cedar -- or pine -- shavings as bedding. Pine is another wood that can emit fumes, so that may form the basis of ACA's opposition to the use of these shavings in feral cat shelters.
