Founder Nikki Linn and Rusty Niedwick stepped onto the carpet in Season 10, Episode 11 in the episode that aired January 20, 2019. Kitty Kasas, the cat houses, pitched in the Pet Products category, one of 61 pet products businesses to brave the Tank across all 17 seasons.
The ask was $200,000 for 20% of the company, an implied valuation of $1M.
Lori Greiner made the deal at $200,000 for 30% equity. That priced the company at $667K, a haircut from the $1M the founders walked in asking for, which is how negotiations in the Tank usually go.
Season 10 saw 92 pitches, and 63 of them closed a deal on air. In the Pet Products category overall, roughly 56% of pitches have landed a shark across the show's history.
The full story
Everything to know about Kitty Kasas
Kitty Kasas are modular, stackable plastic cat houses designed to snap together into custom configurations and wipe clean easily, unlike fabric or carpeted cat furniture that traps hair, odor, and pests. Founders Nikki Linn and Rusty Niedwick built the system to be hygienic and rearrangeable, letting owners add cubes and connect them into towers or tunnels as their needs change. The hard, washable surfaces were the central selling point.
The pair pitched in Season 10 asking for two hundred thousand dollars for 20 percent. The pitch sparked one of the more heated bidding moments of the season, with Kevin O'Leary and Lori Greiner clashing as both went after the deal. Greiner ultimately prevailed, agreeing to invest two hundred thousand dollars for a 30 percent stake after some back-and-forth on the equity.
Kitty Kasas stood out for the drama between the sharks as much as the product. The modular, easy-to-clean design addressed a genuine frustration for cat owners, and the on-air fight between two heavyweight investors over a pet product made for memorable television and signaled real confidence in the concept.
Where Kitty Kasas is now
As often happens, the televised deal with Greiner did not ultimately close after filming. The product, however, found a strong path to market anyway. Kitty Kasas was acquired by pet-products company Jolly Pets in 2019, which brought the modular cat houses into a larger distribution network and onto the shelves of national pet retailers.
Kitty Kasas remains available in 2026 under Jolly Pets. The modular cat houses and accessories are sold through the Jolly Pets website, on Amazon, and at pet retailers including Petco and Pet Supplies Plus. The acquisition gave the brand the retail reach and stability that a small startup would have struggled to build alone.
Where to buy Kitty Kasas
You can buy Kitty Kasas through the Jolly Pets website, on Amazon, and at pet stores such as Petco and Pet Supplies Plus. The system is sold as individual cubes and bundles you connect into houses, towers, and tunnels, all made of hard plastic that wipes clean. For owners who want cat furniture that is easy to sanitize and reconfigure, it is a practical, durable alternative to carpeted condos.
