There is no cause for concern. This is a normal part of the weaning process. The mammary glands should gradually get smaller and the milk production will eventually stop. It may take a couple of weeks for this to happen. In the meantime, monitor the mammary glands to make sure they do not become painful, red and more swollen. This may indicate [mastitis](https://www.petcoach.co/question/?id=46002) which requires immediate medical treatment.

    It sounds like the mom has weaned these kittens herself, so don't worry about her milk production--it will stop now that she has stopped nursing and her breast development will start to go down and she'll "dry up." If the kittens are eating solid food, then provide them with constant access to food and water, and schedule an appointment with your veterinarian for deworming and vaccinations. If you can catch the mother, it'd be ideal to have her spayed. Good luck!

    The best way is to do nothing. The pressure will build up in the mammary glands and tell them that no more milk is needed and then they will stop producing milk. Should they turn red, hot and very painful, then she may have mastitis and Mama needs to be seen by a veterinarian. But if they are just full, wait about a week and they will go soft and start to get smaller by themselves and stop lactating.

    After taking the kittens away it is normal for the mom to become engorged .. over the next couple of days it is important to monitor that she is eating well, drinking well, and does not seem to be in pain. The milk takes time to go away and this can take up to one week.
