I have a Persian cat and have bred her twice. First litter had 2 kittens, the first was stillborn and the second survived but mother never produced milk. The second breeding only produced 1 kitten that presented with the placenta passing before the kitten resulting in another stillborn kitten. Anyone ever have this problem?:(

If it were a human, I'd say it's because the placenta developed to low in the uterus. But what I really want to say is that you should go talk to the person that you got the cat from, and tell her about the issues that you have been having, since this could be a genetic issue, and the breeder may want to review her breeding program. And YOU should get that cat spayed, since she is obviously not a good breeder, and you do not want to pass those genes along if this is a genetic issue.
