5 hours is a long time between births, she may only have had a single kitten, but…if you are bothering her a lot, she feels stressed, she may be delaying labor.
Is she still showing signs of contractions, straining?
I’d keep a close eye on her, but, don’t disturb her too much.
If she is showing signs of straining but no birth she may have a large kitten stuck in the birth canal, or a breech kitten.
You will know by her behavior, and, if this is the case she will need emergency attention.
Let us know!
