Is it safe to spay a mom cat with full milk after kittens are weaned?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | unspayed

I have an appointment to get a mom cat spayed tomorrow and she is full with milk. Her kittens are almost 10 weeks old and are weaned. Is it safe to spay if she has breasts full of milk?

If Naomi still is full of milk, there is potentially more risk of bleeding and/or infection. We generally recommend that kittens be kept away from mom and not allowed to nurse for at least 2 weeks before the mom is spayed. I would recommend contacting your vet today and let them know what is going on and have them help you decide if you should delay her surgery. Good luck! I hope that was helpful.
