Best powdered milk replacement and beyond. I use it as an add on in my chicken puree to add flavor and nutrition. It doesn't clump like other brands but leaves a smooth texture which cats love. I have currently 5 and 3 of them love homemade so I have this item on auto ship.

Kitten loves this milk

I’ve tried another more expensive brand and my little guy loves this brand the best. Also less expensive. :)

Easy to prepare

My little rescue kitten loved this in between wet food. I wanted to make sure he was getting enough nutrients and this was the perfect addition.

Less expensive alternative

Hartz kitten milk replacer is less expensive than the PetAg version but seems to be just as effective. The kittens are gaining weight and developing nicely.

I bought this milk powder incase the kittens needed to be provided this milk. Luckily the mother cat was great at feeding her babies. The good news is that you can use this milk powder and mix it with the mother cat's food, as this helps nourish the kittens as well!!! Nothing gets wasted.

Quick to mix and feed.

I have a large feral colony of cats. This comes in handy when the babies need a little help switching to dry food.
