How do I switch my cat from the litter I am using to Next Gen litter?

Some of our customers have switched their cats successfully at one time without any problem, however we realize that cats are individuals and have their preferences.  In case your cat is confused by the sudden change in litters, Next Gen suggests transitioning the litter box gradually:

Week 1               75% of your current litter and 25% of Next Gen’s Litter
Week 2               50% of your current litter and 50% of Next Gen’s litter
Week 3               25% of your current litter and 75% of Next Gen’s litter
Week 4               100% Next Gen’s litter
