Jonny Cat liners utilize a heavy-duty plastic construction engineered for enhanced durability. This solid material typically features a higher gauge and superior tensile strength compared to standard liners, often exceeding 1.0 mil thickness. These properties provide significantly greater resistance to punctures from sharp cat claws or the impact of heavy litter clumps. The material's integrity is paramount for preventing leaks, especially in frequently used litter boxes where vigorous digging is common, ensuring the liner withstands repeated stress without compromising containment.

The Jumbo 15-gallon capacity is a key indicator of its expansive coverage. A 15-gallon volume equates to approximately 57 liters or a flat lay dimension of roughly 30x36 inches. This generous size is engineered to comfortably fit most traditional, open-style litter boxes, including larger models with footprints up to 18x24 inches or more. It ensures the liner extends sufficiently up the sides of the box, preventing litter from scattering outside the perimeter and accommodating deeper litter beds for feline comfort.

Cats possess a highly developed sense of smell, often over 10 times more sensitive than humans. Artificial fragrances or strong perfumes commonly found in scented products can be overwhelming and may deter them from using their litter box, leading to avoidance behaviors. Jonny Cat liners are formulated to be unscented, meaning they contain no added perfumes or masking agents. This absence of volatile organic compounds (VOCs) creates a more natural and less intrusive environment, encouraging acceptance and regular use of the litter box by sensitive felines.
