That is good news that mother and baby are OK. It's a good thing you brought her to the vet when you did.
I'm going to be the bad guy here, but since this board isn't about making friends, but educating on cat breeding, here goes. . .
<<<no profit in this litter>>>
It is considered a major faux pas in the cat/dog world to be breeding for profit (especially admitting it). The old saying goes "you won't make a profit if you are doing it right." Your girl's c-section is testament to that.
Breeding Persian cats, or any breed for that matter, is a VERY expensive *hobby*, especially if one is doing it the right way. With Persians/Himmys that includes a PKD (polycystic kidney disease) ultrasound of breeding cats' kidneys, *before* breeding, to make sure they won't pass this unfortunately very common (in Persians/Himmys), degenerative, kidney condition to their offspring. Being a dominant gene, 50% of offspring can expect to inherit the condition if one parent is positive, more if both parents are.
It also gets expensive because when kittens are kept with mom for the proper age of 14-16 weeks, this will include both sets of kitten shots, worming, treating any illnesses the kittens get, etc. at the vets. If a breeder is very responsible, they will spay/neuter any kittens being sold as pets before placing them. All of this cuts very much into any profits one might make. If you show cats and want to try to title Mom before breeding, one can kiss any profits goodbye.
That said, again, I am glad that all turned out OK, I hope he grows up to be a beautiful boy.
