I'm sorry to hear of your sleeping kittens - but congratulations on the 2 remaining babies. I also breed Raggies.

There could be many reasons for stillborn kittens. Have your girl and the stud you used been tested prior to mating for FIV/FeLV?, are their pedigrees compatible? Did your girl deliver earlier or later than expected? Have there been any signs of infection or illness through the pregnancy?

Sometimes these things just "happen". As the kittens were born Tuesday/Wednesday, it's probably a little late to take them to the vet for testing. I'd pop your girl and the babies to the vet for a quick postnatal check up just to make sure they're all doing well.
