Couldn't find the heartbeat,where the baby? in Life of a Mama Cat

I didn't feel the baby move most of the day. I was so worried I was debating on going to hospital. I took a Doppler and couldn't find the baby. My husband suggested my mom try to find the baby. My mom checked for several minutes to discover the baby hiding up under my right ribs. I didnt even know they could reach up that high..at least now when my ribs hurts I know it's the kid testing my boundaries.
