Can Kittens Drink Milk? Things You Need To Know!

can kittens drink milk

I remember from my childhood when I visited my grandparent’s house in the countryside my grandmother gave kittens to drink milk, but how is it in reality? Can kittens drink milk? To this and other related questions about kittens feeding, I will answer them in this article.

Usually, kittens are weaned off from mother’s milk around the age of 4 weeks and are eating solid food from 8 weeks. When is the right time to wean off your kitten you can say by teeth showing in her gum so you know it’s time? After that, most of the time kittens lose the ability to digest the major carbohydrate called lactose which causes a lot of allergic reactions and also diarrhea not only in felines but also in humans as well. So turns out my grandmother was wrong, giving cow’s milk to kittens, or these kittens were not lactose intolerant. From my experience, a lot of kitten and cat owners make this mistake, giving them milk that is not suitable for kittens. So here is an explanation can kitten drink milk and also the list of milk to avoid and to give:


Do we know how important mother’s milk is for humans but is it different for kittens? No, it is not! Once the mother cat has given birth to her little baby, her milk is full of colostrum levels, and it helps to boost immunity, building a better protection from all sorts of illnesses. Without colostrum, kittens’ immunity will decrease. Vets say that the first 72 hours after birth are usually with the highest amount of colostrum, and then every week it starts to decrease. There is nothing that can be equally good as a cat’s mother milk because it has the right quantity of proteins and other good nutrients.

Only when the kitten does not drink its mother’s milk, she can have another source of milk that is suitable for her. There are some tips when you can feed a kitten with milk:

✅ The kitten is fully weaned.
✅ The mother cat is suffering from illness such as mastitis or is deceased.
✅ The mother does not produce milk anymore.
✅ The kitten needs some special care.


Kittens have very sensitive stomachs and even this type of milk in small amounts is much better for their stomach than cows milk, but these are empty calories and still in big amounts can cause problems that we do not want. Almond and soy milk can also contain a lot of sweeteners and preservatives. So the short answer is, do not use soya and any nut milk. There are some reports of kittens having allergy reactions to nuts and signs are loss of fur, diarrhea, vomiting, and swelling around the mouth or inside.

A small dish of soy or almond milk with sugar is equal to a human eating 3 doughnuts, and it can cause extra weight for your kitten. That is not good if you want your cat to live a long and healthy life.


Goat milk as well is not good for your kitten because it does not provide necessary nutrients for carnivores. As I mentioned before, most cats are lactose intolerant and can not digest goat’s milk. But of course, there are many stages of lactose intolerance, and some kittens might have small amounts without any problems. Also, another bad ingredient for kittens is fat because your feline does not need more fat in their diet.


Cows milk contains lactose as well so it is not suitable for baby kittens and should be avoided at all times. Kitten’s little stomach is very sensitive and she will get diarrhea and dehydration that is very dangerous and need vet help.


Kitten formula is the second option after mother’s milk and it is good to use for example when a kitten’s mother is not around, is sick, or can not produce milk anymore. So in this case kitten milk formulas like PetAg KMP powder or Hartz Kitten Milk Replacer are very good options.

Usually, milk replacers contain:

✅ Probiotics and prebiotics.
✅ Vitamins and minerals that support a kitten’s growth and development.
✅ Formulated similar to mothers milk proteins, carbohydrates, and fats.

Unopened powders should be kept in a dry and cool place, but mixed milk replacer in the refrigerator. Do not keep it longer than 24h in the refrigerator. Feed your kitten with 2 tablespoons of liquid per 115 g (4oz) of body weight every day. When your kitten is already grown up and eats solid foods you can give 1 tablespoon per 2.2 kg (5lbs) body weight. But you always need to read the instructions on the package to be sure.

Make sure to warm it up and always test some drops on your hand to check is it not too hot. Never use a microwave. It can happen that your kitten has some constipation and in this case, you can add up a drop of vegetable oil. It is always a good idea to consult with your vet about the kitten’s health and feeding processes.


Hopefully, you had some guidance after reading this blog and got the answer can kitten drink milk. Cats are carnivores and should eat food that is full of vitamins, proteins, and minerals. Especially it is very important for kittens to grow healthy and happy. This is why a cat’s mother’s milk is so valuable because it provides all nutrients your kitten needs. After they get weaned off and start eating solid food milk can be given as a treat of course only if your feline likes it and there are no health issues.
