In the first week after bringing a kitten home, the food bowl slid all over the kitchen floor and kibble scattered everywhere. You stood in front of the food shelf, holding two different bags, wondering which one truly suits a tiny creature growing week by week.
Dry food for kittens is not just smaller kibble. Formulas for this stage usually emphasise protein for muscles, nutrients for brain and eyes, and a still-developing immune system. Kibble size matters too: bite-sized kibble helps a kitten chew and digest more easily.
The five choices below go from a 7 lb bag for daily use to a 3.5 lb bag to try first, and a grain-free formula for homes wanting that direction. The product order stays the same, only the wording is new.

Conclusion
Whichever bag you choose, the transition matters as much as the formula itself: mix the new food with the old over several days, watch stools and enthusiasm for meals. Kittens grow fast, so today's portion may no longer be right after a few weeks.
If a kitten refuses food for a long time, loses weight, or has diarrhoea that won't stop, that's something to ask a veterinarian about instead of just switching to another bag.
