A new food.
A little at a time.
Give their next food a gradual introduction. Turn the change into a dated schedule, with clear proportions and a pace you can adjust.

Feeding notes
Only increase the new food if your pet is eating and tolerating the change. If problems develop, ask your vet how to adjust the plan. Persistent vomiting, liquid diarrhea, pain, or lethargy need veterinary advice. [3]
If a cat stops eating, contact a vet promptly; do not wait for the next stage. [4]

ROOM TO GO SLOWER
Their appetite
sets the pace.
A schedule helps everyone in the household follow the same instructions. It still needs to fit the animal in front of you.
Add meals to your weekly care planWhy change food gradually?
AAHA advises a gradual introduction to reduce digestive upset and food aversion. Its dog example spans seven days; cats may need several weeks. Adjust to acceptance rather than treating a finish date as a deadline. [1]
Is there one proven best schedule?
No. WSAVA notes that evidence does not establish one transition method as best for every pet. It describes a gradual 7–10-day change as useful for some animals. Your vet’s assessment takes priority. [2]
What do the percentages and portions mean?
They are fractions of each food’s own full daily ration. At 25% new food, use 75% of the current food’s daily amount plus 25% of the new food’s daily amount. For example, 200 g/day current and 160 g/day new becomes 150 g current + 40 g new. They are not percentages of a fixed bowl weight or volume. [3]
What if my cat refuses the new food?
Keep adequate food intake the priority. Some cats accept a new food better alongside their familiar food, rather than mixed in. A cat that stops eating needs prompt veterinary attention; never try to force a switch by withholding food. [3] [4]
How is the schedule calculated?
The 7-day example assigns two days each to 25%, 50%, and 75% new food, then shows 100% new food from day 7. The 10-day option uses three days per mixed stage; the 14-day option uses five, four, and four. Custom pace lets you set 2–30 days per mixed stage. Longer timings are Voffi planning adaptations, not separate protocols prescribed by these sources. The last date marks the first planned day of new food only, not a one-day feeding limit.
Optional portions multiply each food’s full daily ration by its stage percentage. The tool does not select foods, prescribe a diet, calculate calories, or evaluate symptoms. For medical diets or a pet with special nutritional needs, use your veterinarian’s instructions.
