PrettyLitter is a silica crystal litter that changes color when it meets urine outside a typical pH range or with blood in it. The pitch is that you're already looking at the litter box every day, so the litter might as well tell you something. It can't diagnose anything, and the original formula trades away the clumps you'd otherwise be reading.
We analyzed 192 owner comments across 4 YouTube reviews, published between 2020 and 2025. Only 2 of those comments name PrettyLitter directly. Most are reactions to the videos themselves, so treat the numbers below as the mood of people watching PrettyLitter reviews, not as 192 verdicts on the product. Of the comments with a clear sentiment, 69 were positive and 10 were negative (87% positive). The themes that came up most were smell and odor (41 comments touched on it) and price or value (31). The most-liked comment, at 761 likes, wasn't about performance at all. It pointed out that you could buy the litter at a store instead of on a subscription.
If you use a clumping litter, you already collect a daily data point without trying. Bigger or more frequent urine clumps than usual can be an early sign that a cat is drinking and peeing more, and that change is worth a vet call. Owners who scoop daily tend to spot it first.
Original PrettyLitter changes that trade. The company describes it as a non-clumping silica gel litter: the crystals absorb urine and trap odor while the water evaporates. You scoop the solids, stir daily, and replace the whole box about every 30 days. So you lose the clump-size signal, and in exchange you get a color signal. The company also now sells a separate clumping version, which adds a guar-gum binder. If clumps matter to you, check which formula you're buying.
PrettyLitter publishes its own color chart. Dark yellow to olive green is what it calls typical. Blue, it says, may indicate an alkaline pH consistent with urinary infections or a higher stone risk. Orange, it says, may indicate an acidic pH. Red, it says, indicates the presence of blood. Those are the manufacturer's claims about what a color is consistent with. They are not a diagnosis, and a color in the box doesn't tell you which condition is behind it.
Used honestly, the color is a nudge: something changed, so call your vet and bring a fresh sample if they ask for one. It also only reflects what one cat did in one spot. In a multi-cat home you won't know whose urine it was.
Price is the recurring complaint. Silica crystals are sold as lasting longer per bag than clay; the company says up to twice as long as clumping clay litter. Even so, comments kept coming back to cost and to the subscription. The company now sells one-time purchases as well as subscriptions, and lists stores including Target, PetSmart, Petco, Walmart and Amazon, so you don't have to subscribe to try it. Odor was the other big theme. Crystal litter only controls smell if you stir it, scoop solids daily, and fully replace it on schedule.
you have a single cat (or can watch which cat uses which box) and want an extra early-warning prompt to get a vet check, and you're happy to pay more than clay for it.
you rely on reading clump size, you're on a tight litter budget, or your cat dislikes the feel of crystals underfoot.

A color change in the litter is a reason to call your veterinarian, not a diagnosis. Never use it to rule a problem in or out. A cat that strains in the box, goes often in small amounts, cries while urinating or has blood in its urine needs a vet promptly. A male cat that can't pass urine is an emergency. Consult your veterinarian for individual pet health decisions.
You already run a daily health check every time you scoop. PrettyLitter swaps the clump-size signal for a color signal. That's a fair trade if you have one cat and will act on a color change by calling the vet. It's a poor one if you'll treat the color as a diagnosis or resent the price.
