The Problem

Your cat's litter box tells a story.
You're just not hearing it.

Veterinarians ask about litter habits first.
What if you always had the answer?

Every visit to the litter box reveals something about your cat's health:

How often

How often

Visit frequency reveals urinary and digestive health patterns.

How long

How long

Time spent in the litter box can indicate discomfort or strain.

When

When

Changes in timing and routine often signal stress or illness.

How much

Waste amount tracks hydration, appetite, and digestive function.

Body weight

Gradual weight changes — detected before they become visible.

Trends over time

Is the pattern normal for their age and breed? We track it for you.

All this data flows in front of you every day — but without the right tools, you can't capture it.
