1. Why Sudden Food Changes Can Cause Digestive Upset
Cats have sensitive stomachs. Abrupt dietary changes can lead to vomiting, diarrhea, or food refusal.
2. The 7-Day Food Transition Plan
Mix the new food with the old:
- Days 1–2: 25% new, 75% old
- Days 3–4: 50% new, 50% old
- Days 5–6: 75% new, 25% old
- Day 7: 100% new
3. Signs of Food Rejection or Intolerance
Watch for vomiting, loose stools, itching, or refusal to eat. Return to the previous diet and consult a vet if symptoms persist.

4. What to Do if Your Cat Refuses New Food
Try warming the food slightly, mixing in a small treat, or using food toppers. Some cats prefer wet over dry or vice versa.
5. Rewarding Positive Eating Habits
Offer praise, petting, or a favorite treat after successful meals. Positive reinforcement helps reduce food anxiety.
