How do I no please help

Can some one please help me how do I no if my cat has finished giving birth please my princess gave birth to 3 kittens last night and number 4 came this afternoon between 3 and kitten 4 she has slept ant eaten but she is still pawing her blankets xx

If it's been about 6-10 hours since the last kitten came, I would say it's a safe bet she is done.  Most litters are about 3 or 4 kittens, sometimes 5 but usually 3 or 4.  You can also gently feel her abdomen and see if you can feel any more.  But if you're not used to it, you won't know what you're feeling for.  She's probably done.  Mommas will often "knead" blankets while nursing, too. 

It is not sure you really need the answer.  Cats can deliver many times apart. So if she is contend and not in trouble, happy with her kittens, you can await keeping an eye on them, even if you suspect there is one left.

If she is visibly in distress, first now you have a problem: one left and the labor going on, OR in distress because from other reasons.  In this case best to contact a vet, at least phone.

Prolonged unfruitful labor is not good, the last should got easier than the first.

Good luck!

Thank you she is very happy not in any distress at all
