Katris is the modular cat furniture system from Papercut Labs which actually makes living rooms look more stylish.
The modular cat furniture is made up of over 200 layers of sustainably sourced cardboard. In addition to being perfect for kitties' claws, this material makes it extremely durable -- under normal conditions, Katris modules can withstand a year of scratching. The cardboard layering also makes the modular cat furniture very strong. Katris can hold up to 300 pounds of weight, so even the biggest, furriest cats can climb on it as much as they want.
Best of all, Katris modular cat furniture is extremely open to customization. The block-like pieces come with different sets of covers, so that they can be colorful, black and white or wood patterned to fit in with any decor. They can also be configured into many different shapes and designs to suit cats' and owners' tastes.
