Why have we changed the Purina ONE dry cat formulation?

At Nestle Purina Pet Care we regularly review our formulations to ensure that they deliver excellent nutrition for your cat. We base this on the latest research from both our own studies and studies carried out by other researchers in the field of pet food and nutrition. Specifically for new ‘Purina ONE with Immune Defence Plus+’, we have focused our formulation modifications on ingredients that will help support your cat’s immune system.

How should I transition my cat to this new recipe?

Once you have purchased a bag of PURINA ONE, we suggest you transition your cat over a 10 day period as follows:     

Day 1:

Replace about ¼ of your pet’s usual food with the new food. Mix it with the old food and feed as you normally would. Continue to feed like this on Days 2 and 3.     

By Day 4:

If your cat has tolerated the initial change well, increase the level of new

food to half of their daily feed and continue for Days 5 and 6. Do not worry if your cat has not adapted by Day 4, just take it slow and give them a few more

days at the lower level. 

By Day 7:

If your cat continues to tolerate the new food as a portion of the diet,

increase this portion to ¾ of your cats daily feed and continue for Days 8 and 9. Again, if your cat takes longer to adapt, just adjust as needed. 

By Day 10:

If your cat has continued to adjust well to the gradual change in their diet, then they will be ready to switch to the new food completely.
