I used to feed NB for my Westie, since it was a Limited Ingredient Diet. It is an all stage food. Here is what they state on their website:
"Dick Van Patten's Natural BalanceÂ® Ultra Premium and L.I.D. Limited Ingredient DietsÂ® Cat Food is made for All Life Stages and provides premium nutrition for kittens to adults. In Nature, your pets would not have the choice of kitten formulas, nor lighter formulas for their senior years; they would simply live on a diet of mostly meat and and some grain. In a natural free environment, animals instinctively eat more or less, depending on their age and activity level.
The Dick Van Patten's Natural BalanceÂ® Cat Formulas above contain all the nutrition kittens need to grow up strong and healthy!"
