Kits can come almost immediately one after another or it can be hours. Generally they are 15 minutes to an hour a part ... giving her plenty of time to clean each kit ...
If she has not delivered another one, but keeps cleaning herself and checking ... there could easily be another kit or two. It's hard to say without being there.
How old is Kiwi?
How much does the first kit weigh? Does the first kit now seem to be active?
Is there any bright red blood from Kiwi? If so or if she continues to bleed, get her to a vet a.s.a.p.
It's hard to know the amount of time that has passed ... we do not know what time zone you are in.
How long has it been since the first kit was born? Has there been any other kits been born?
Can you see any movements on the outside of the tummy area that would make you believe there is a kit moving inside of her still?
Is she still in labor? (contractions/stretching/panting etc.) Prolonged delivery of kits, once the first kit is born, is not a good sign.
Watch her carefully ... if you see a kit part of the way out, but not coming out (stuck), especially rear end/tail or legs first, you will need to help her finish delivering it ... or get to a vet quick ... if this happens ... call the vet and let them know you are on the way so they can be prepaired and expecting you.
You can call me if you are home with her and still think there is still a problem. (540) 345-7121
