    History of So Phresh Cat litter

    So Phresh belongs to Petco, a US brand that sells pet litters and accessories. With nearly 70 years of experience, Petco has built trust in its customers as an excellent value-for-money brand.

    The house brand So Phresh is no exception, meaning that it provides affordable products with surprisingly good functions, varying in types and materials.

    What kinds of litters does So Phresh provide?

    The most well-known thing about So Phresh cat litters is their diversity in materials. If ever you want to get a new litter, you will find some suitable choices under the So Phresh brand.

    There are three primary materials:

    Standard Clay Litters

    Clumping clay is the most affordable material on the spectrum. It can eliminate feces and urine odors excellently. Thus, we recommend this type of cat litter if you have a tight budget or if you want to keep a fresh linen scent at home.

    Some available clay litters by So Phresh are:

    Silica Gel Crystals

    Compared to traditional clay litters, silica gel crystal litters control odors better. What’s more, this material performs excellent moisture adsorption.

    Some So Phresh silica litters include:

    Biodegradable Cat Litters

    Biodegradable litters are made of plant-based materials such as grass, pine, beet pulp, or recycled paper. Thus, they are “green” and eco-friendly.

    Some So Phresh biodegradable choices are:

    Top 3 So Phresh Cat Litter Reviews

    1. SO PHRESH Odor Control Paper Pellet Cat Litter



    The first So Phresh cat litter to introduce is the Odor Control Paper Pellet. This litter was created to maintain and eliminate urine and feces odors, and we can confirm it does! The combination of paper fibers and baking soda are helpful in neutralizing the ammonia smell without breaking the pellet particles apart. Additionally, it prevents the saturated litter from forming wet messes on the bottom of your litter box. 

    The manufacturer does add some artificial ingredients like baking soda to mask the smell. Fortunately, it is neither overpowering nor off-putting. Instead, the litter features a light and decent “woody” smell. This So Phresh Paper Pellet is not designed to clump. The waste liquid and moisture break down the pellet into soft sawdust-like particles. Once it reaches a certain moisture amount, then it’s time to scoop out and replace the litter.

    We recommend that you scoop the litter regularly as the pellets do not change color or clump. Regular waste removal will ensure that you avoid any sticking to the litter box and the cats themselves. 

    Our final note about this product is regarding the scoop. You need a invest in a scoop with big holes to accommodate the large pellet size. Also, the material of the paper pellets creates less dust and is less likely to be picked up on the cats’ paws. Thus, tracking issues will not be a major concern.

    • Be eco-friendly using biodegradable recycled paper
    • Good moisture-absorption
    • Less dust and tracking
    • Comfortable smell
    • Harder to scoop
    • No specific clue about when to scoop
    • No clumping
    • Expensive

    2. SO PHRESH Extreme Clumping Unscented Grass Seed Cat Litter



    The Extreme Clumping Unscented Grass Seed is another excellent alternative in terms of odor control. Along with its ability to eliminate odor, it’s an effective and ultra-absorbent clumping product. The litter absorbs moisture fast and forms tight and hard clumps to easily scoop later.

    The litter is made of grass seed, which is environmentally friendly and a great option for your lovely cats. You can reduce the carbon footprint of your pets and ensure they are safe even if they digest the litter accidentally. This litter is also biodegradable which makes proper disposal simple. You can compost the litter, take it to the landfill, or even flush the waste in small quantities, although we do not recommend doing so frequently.

    The grass seed particles are small and odor-absorbent which also makes the Clumping Unscented Grass Seed economical to use for two reasons—they dry out quickly and form solid clumps. You can easily scoop out the waste with a standard scoop, without losing the clean particles.

    The 20-pound bag can last a single cat for many months. If you prefer to test out the product before committing to such a large quantity, you can also purchase this litter in a 10-pound bag. A helpful side note, the litter is very soft, which is suitable for kittens with sensitive paws. 

    • Excellently-absorbent clumping
    • Biodegradable material which is safe for the earth and cats
    • Soft for sensitive paws
    • Odor-absorbent litter
    • Easy to scoop
    • A bit expensive
    • Annoying tracking

    3. SO PHRESH Odor-Lock Crystal Cat Litter


    This Odor-Lock Crystal Cat Litter is non-toxic, excellent moisture and odor-absorber without the use of strong scents. It creates an interesting crackling sound when absorbing liquid – which may be a great way of knowing your litter is working effectively but may be a bit of a nuisance in the middle of the night. 

    The crystal gel has a light smell, but it is still decently modest and acceptable. That there are no artificial ingredients making the litter safe for sensitive cats and pet owners.

    The Odor-Lock Crystal Cat Litter is non-clumping. Rather than regular scooping, you will replace the entire litter box once you can no longer smell the gentle litter scent or the gel is completely saturated. We found that the crystals do not stick to the bottom or sides of the litter box. The particles are significantly larger than other litters which helps reduce tracking or sticking to the paws of cats. Scooping is also quite effortless because of this feature. 

    One thing to consider about this litter is the amount of dust that it can create while scooping. However, it settles quickly once the litter is clean and doesn’t pose a tracking issue.

    • Highly absorbent in terms of odor and liquid
    • Odor-lock for several days
    • Lightweight and economical
    • More expensive than many others
    • Noisy at night
    • No-clumping

    Our Overall Results Explained

    Price: 4/5

    So Phresh cat litters are in the middle of the market when it comes to their price. Many consumers find them affordable and economical regarding their quality and materials.

    A 20lb bag of So Phresh Clumping Clay Litter can last one cat several months. Alternatively, there is a portable 8lb package that you can use for travel or short-term use or a substantial 40lb bag to appease your multiple lovely cats. The price is still very pocket-friendly no matter your needs.

    Clumping Action: 3/5

    Although there are many perks to the So Phresh brand, clumping is not one we would include as many of their clumping litters do not live up to our standards.

    We expected waste particles to adhere to each other so that we could scoop them out quickly. However, some of the So Phresh litters turned into a sticky glob and fell apart while scooping. As a result, the litter left behind in the litter box appeared very heavy, dirty, and recycled.

    Odor Control: 4/5

    A common theme among all So Phresh litters is that they fight litter box odor excellently. Specifically, they lock urine smells efficiently and for a long time. Some So Phresh formulas include baking soda or grass seeds to mask the odors and both are incredibly effective. Neither are known to cause any discomfort to you and your cats.

    So Phresh is among our top choices when it comes to odor control.

    Frequently Asked Questions (FAQ)

    Where to buy So Phresh cat litters?

    So Phresh litters are only available through Petco or Amazon. Fortunately, you can easily find Petco locations through their website or you can choose to place an order online.

    Is So Phresh litter flushable?

    Some biodegradable products by So Phresh are flushable down to the toilet. Most are not. Each product will note on its label whether it is flushable or non-flushable.

    However, we still do not recommend flushing waste litters as there is a risk it might cause plumbing problems or health risks. Instead, you should refer to other cat litter recycling methods.
