Overview
Read the full profile
Standard pace: 25% new food on days 1-2, 50% on days 3-4, 75% on days 5-6, and 100% from day 7. Sensitive cats can stretch the whole cycle to 10-14 days, holding each step for three days. Introduce no new treats during the transition so signals stay clear.
Check stool form, vomiting, and appetite daily: formed stool plus normal appetite means advance; soft stool means revert to the previous ratio for three to five days before retrying. Watery diarrhea, blood, or repeated vomiting means stop and see a vet rather than forcing the transition through.
Transition even between flavors of one brand, since formula differences can upset the gut. Log reactions at each step to build your cat's personal transition profile and reuse the safer timeline next time.

Owner questions
My cat picks out only the new or old kibble. What now?
Switch to scheduled meals to raise motivation and mix thoroughly; if pickiness persists, slow the transition and ask a vet to rule out oral pain.
