KUS is a pet-focused brand founded in 2021 by Katya, who runs the workshop, and Alyona, who leads the project. The company creates practical window protection and comfortable furniture for cats and dogs, combining safety with designs intended to complement home interiors. Its removable, no-drill window screens are made to measure by customers, with video guidance for installation and options for standard and tilt-and-turn windows. The range also includes cat balconies and hammocks, shelves, mosquito nets, tilt-window guards, pet beds, houses, and travel products such as car hammocks for dogs. Customers can also purchase gift certificates and accessories.

KUS makes orders within 7–14 days, including during peak season, and ships through SDEK or by mail, with delivery available internationally; shipping costs are not included in product prices. The founders say their products are developed with input from dog handlers, feline specialists, and veterinarians, and that they conduct crash tests. KUS also states that part of its profits supports animal shelters, reflecting its aim to make pets’ lives safer and more comfortable.
