Litter-box health monitor
Earlier detection, better decisions.
Odor sensing
Combines ammonia and sulfur readings to catch odor changes before they fade into the background.
Visit frequency
Counts litter-box visits over time, helping owners spot changes in routine instead of relying on memory.
Duration monitoring
Pairs odor data with how long each visit lasts, making changes easier to understand.
Light alerts
Green means healthy, yellow flags abnormal changes, and steady red signals a serious alert.
