## Dead Ends

- **** — Owners think lactose-free milk is safe, but it still contains proteins that can cause allergic reactions or gastrointestinal upset in some cats. (75% fail)
- **** — Giving small amounts of milk as a treat thinking it is harmless, but even small amounts can trigger diarrhea in sensitive cats. (80% fail)
- **** — Using goat's milk as a substitute, assuming it is lower in lactose, but it still contains enough lactose to cause issues in intolerant cats. (70% fail)
