that is a really interesting question. i am going to keep checking back to see if anyone knows!
I would love be part of those miracles - maybe I can do it someday !
Unfortunatelly I dont think this kind of service is avaliable anywhere in my country ( Brazil) but ...
I was wondering cats could do that because I know the hormone ( ocitocine)for is produced at the brain level not ovaries and stimulated by sucking - at least its the way it works with humanes. But maybe cats are different, I dont know...
I dont think that the proper hormonal things will happen to start up her milk, even tho the equipment is still there. Whether milk could be induced by a vet, i dont know.
However, she might still enjoy the company of kittens and be a great foster mama even tho she cant nurse the kittens..but her hormonal changes may decrease her interest..Kittens who arent properly socialized by Moms and siblings can be misfits. 2 of my cats were removed from their mothers too early and are not nearly as smart and sweet as the one who got 6 or 7 weeks of good home training. So maybe you two might partner to provide fostering for abandoned kittens - you provide the food and she does the rest! If you really want to try it, some cageless shelters need volunteers to do such miracles.
