Does anyone have a nursing mama cat?

Description

I have been taking care of 5 orphan kittens since day 1, since their mom died. They're 2.5 weeks old. One of them likes to suckle on his siblings genitals any chance he gets which is very dangerous for his siblings. The vet said this is because he has no mom to suckle on whenever he wants. I have to keep him separate from the others now but I don't think this is good for him and would like to find him an actual mother cat if I can. Please message me with pictures if you have a nursing cat who would be willing to care for him.
