KMR Milk Replacer for Kittens is a commercial formula designed to substitute for mother’s milk when hand feeding newborn kittens.


It’s not easy to hand-raise newborns, and it’s especially important for them to have a milk replacer like KMR to give them the best chance for survival.

Nutritional Value of  KMR Milk Replacer for Kittens

Newborn kittens cannot thrive on cow’s milk. A cat’s milk has much more necessary fat and protein specifically for the needs of a growing kitten.

Although milk from the nursing queen is the best (especially the colostrum during the first several days after birth, due to added immunity boosters) many newborns become abandoned or orphaned, and a surrogate queen isn’t always available.

The KMR formula is the closest approximation to a natural milk source for kittens. Click here for more info

Formula Varieties

kmr-milk-replacer-for-kittensKMR Milk Replacer for Kittens comes in two forms: liquid and powder.

The liquid form of KMR is the most convenient and is less likely to clump, but once opened it must be used within a day or two, so could be wasted if you’re only feeding one kitten.

The KMR powder is more economical because you mix it yourself with water, and you can mix only as much as you will need per feeding.

However, when bottle feeding kittens the nipple can get plugged if the KMR Milk Replacer for Kittens formula is not mixed well.

It’s worth experimenting to see which works best for your situation.

How to Administer KMR Milk Replacer For Kittens During Feeding

You need to warm up the KMR formula to room or body temperature before feeding.

You must shake the KMR Milk Replacer for Kittens well and refrigerate after opening. Discard any unused portion after 72 hours, and do not freeze.

Note: If you cannot get immediate access to KMR, you can try this homemade kitten formula recipe to use in an emergency. Don’t use long-term, as it is based on cow’s milk.

Kittens only need to be fed KMR milk replacer until they are 4-5 weeks old. Once they are able to be weaned, you can mix your nursing formula with Pet Ag 2nd Step Weaning Food to allow the kitten to gradually transition to solid food.
