## Root Cause

Adult cats have low lactase enzyme activity; lactose in cow's milk ferments in the colon, causing osmotic diarrhea, dehydration, and electrolyte imbalance.

## Dead Ends

- **** — Using lactose-free milk—still contains proteins and fats that can cause digestive upset; cats don't need milk. (60% fail)
- **** — Giving small amounts—lactose intolerance is dose-dependent but unpredictable; chronic diarrhea leads to dehydration. (70% fail)
- **** — Switching to goat's milk—still contains lactose; only slightly lower than cow's milk, same intolerance risk. (80% fail)
