2. The Cat Owner's Guide to Kitty Litter Options, Caroline Golon, August 5, 2014
Cat author and activist Caroline Golon offers her take on the pros and cons of different types of cat litter.

She also offers information on how to transition a cat from one brand or type of litter to another. Her bottom line advice is that "While many litters offer benefits like odor control and clumping abilities that make life easier for humans, the most important thing is how your cat likes it."

That's not surprising as Golon notes in an article on "4 Innovative Cat Litters to Try" that she never posts a review of a poor litter. Keeping in mind that what her cats like, other might not, she adds "What I talk about on this site is always deemed worthy of at least a test run if you think it will work for you."
