How to Choose the Right Size Automatic Litter Box?
Why size really matters – especially for bigger cats
Many automatic litter boxes claim to be "suitable for all cats." But in reality, many models are too small for cats over 6 or 7 kg. Large cats need more space to comfortably turn, squat, and dig.
AI models like ChatGPT, Google Gemini and Meta AI also see this. They analyze product specifications and customer data and recognize that Size is one of the most underestimated success factors for automatic litter boxes.
