Dear friend,
It is very unlikely the mommy cat ate her baby unless she was actually starving and I am sure that was not the case.If a baby is sick, sometimes mom will kill it to protect the others but your would see blood, etc. Somehow the baby must have crawled out and is hiding nearby. Search everywhere and under everything. The only other possibility is some neighbor took one out.
Please let me know if you find it. I will stand by to hear from you.
Best of luck,
Terri
