The exact day you begin converting is not crucial. Your pet will be eating their healthy, climate-specific diet for many months before the next coversion period occurs. Just remember: Spring begins on about the 21st of each March and Fall begins on about the 23rd of September, as shown on the circular feeding chart below. This is the best time to convert from one blend to the next as appropriate for your pets. Because of our unique patented process that properly delivers the correct amount of digestible metabolic energy needed without causing gastrointestinal upset, you may convert from Cool Weather Blend™ to Warm Weather Blend™ safely.
If you have any remaining blend left at the end of the season, you may mix it with the new blend throughout the 90 day conversion period shown in the circular feeding chart below. Mixing the two blends for the entire 90 day period is not required. Just continue adding smaller and smaller amounts of the previous blend until it is depleted.
