how much longer???

I took in a pregnant cat. I have no idea how far along she is. But she is already showing. Her nipples are huge. No sign of milk though. She is still eating and drinking. Her temperature is 100. She stays in her nesting box all day. I can fell the kittens kicking. If someone can tell me about how much longer she has that would be great.

She is gorgeous!  We too are unsure how far along exactly Lola is, though her most likely due date (from when we saw a couple of toms hanging around) will be 3rd May.  Doing the same as your little girl though for the last couple of days can even see the kittens moving about when she lay half way across the room!  Let's hope all our kittens and mama's stay safe and well 

The exact day and hour is impossible to tell.   the best bet is, when you can feel the kittens move, it is max 3 weeks left, more often about 2.   (depends also on how good with palpation you are).

Not even measuring of the temperature is a safe thing, although it can give a forewarning - it usually drops about 3 grades Fahrenheit  several hours before delivery.

Although, I recommend, if you really want to measure temperature here, measure in the foreleg armpit, or with such a modern ear thermometer.  Not so exact as in the behind, but much less stressing on them.

Good luck!
