About the Manufacturer

Pioneer Pet and Smart Cat began over twenty years ago when Betsy Lipscomb, the founder and president of Cats International, gathered old wooden fence posts from her farm in Wisconsin and gave them to cat owners to use for scratching posts. The posts were very popular and over the years were improved with the addition of sisal rope and a sturdy base.

When they enter a product category, their intent is to always fundamentally rethink it. Innovation is the key to what they do. Take fountains for example. For decades, dog and cat fountains had been complicated plastic contraptions that were pretty much impossible to keep clean. So they started with the basics, from the perspective of the pet as well as the pet owner. Cats and dogs need fountains to keep their drinking water clean and fresh. So what’s the simplest way to filter and circulate their water? The answer was a bowl-inside-a-bowl design that looks as simple, fluid and seamless as water itself. To top it off they made their fountains out of easy to clean quality materials that fit right in with the best of modern furnishings.

Their company was conceived with the unique mission to provide products that are specifically designed to enhance the quality of life for animals by providing for their behavioral needs. This mission is what sets them apart from other companies. With their high quality design and construction, they encourage the mental and physical stimulation of animals. The products are designed by behavior experts and all are widely tested and approved before reaching the market.

Their extensive manufacturing capabilities have taken the farmhouse kitchen operations to new heights. The mission, however, is still the same: to provide superior products that will improve the quality of life for pets and their owners.

Kitty loves it!

Jane from Rochester, MI– Verified Buyer

Color is beautiful. Item a little larger than expected, but looks like a miniature bath tub. The higher sides and slickness of material make for both keeping contents in the 'box' and for easy cleaning. Kitty loves it and it is her PREFERRED box! What else matters?

Prevents flying litter

Nita from Lenoir City, TN– Verified Buyer

Some cats can be too energetic when they put their paws into litter and I find it has been tossed all over the laundry room floor. This is a sizable litter box with high sides that really do help to contain that flying clay. Very pleased with the product.

Ultimate Litter Box

Anonymus from Utah– Verified Buyer

These are too narrow. They really need to be wider. The cats have a hard time turning around, and when they do they end up stepping in doo and making a bigger mess. I like the design and the tall sides. It just needs to be wider.

Just As Described

Best of ots kind

Jeanine from Staten Island, NY– Verified Buyer

Perfect for a cat who likes to kick the litter around

the perfect litter box

Al from New York, NY

The curved shape makes cleaning and scooping easier and faster that any litter box we have ever had. No corners to trap messes.The lower entrance and higher sides add to i's practicality. The translucent color is attractive (though this has never been a consideration. We have had 20 cats over a a period of 37 years, and this is the only litter box to ever consider,

Just not the right one for me

pj0908 from Texas– Verified Buyer

Arrived very quickly. Like the color and shape is nice. I like the high sides but, for some reason, I thought it was bigger. It was for my 25 pound Rag Doll but that's my fault.
I have who stands to urinate and the high sides help here - as long as he's not facing the opening.
Good value but I just needed a bigger one.

Cats LOVE it!

Lorna Loomis from Kanata, ON– Verified Buyer

Design is simple, yet our three cats couldn't wait to use it and have been happily using it ever since. No adjustment period was required. I ordered three of them and want to buy one or two more!

Best Litter Box

Kansas24 from Missouri

I have 2 large cats that kick litter out of the box and they also don't fit in most litter boxes, these work great! They are so easy to clean and really well made one piece plastic with no nooks or crannys or edges to catch old litter. So far they don't seem to scratch easily. The high back does keep litter in even if the cats get carried away pawing at the litter. The cats took to them first thing and the old ones went in the trash!

The cats seem to like it

aa from Pomona, CA– Verified Buyer

I have two cats and even though I had a big litterbox they would sometimes miss the box. They seem to like the box and I haven't had a miss yet. The only problem is that the front is a little too low, when they scratch to cover up their feces, they tend to send the litter flying out the front of the box.
