Hi everyone! I hope someone can help me with this problem...
My cat Jellie gave birth to 4 babies today and all were stillborn.

This is her second litter. The last litter she had 3 live, 2 stillborn, and one die the next day. She also delivered a baby on Wednesday that was stillborn too. She seemed fine and I could feel the babies moving around. I called the vet who didn't seem concerned and didn't think I should come in. I also read some articles online that said it is common for cats to expell a dead kitten and still deliver the rest of the litter normally. So I let it go. Now I'm feeling like I should've done something more. I feel horrible, guilty, and disappointed! Any thoughts?
I also want to know when or if I should breed her again?
Thanks.
