Pregnat cat

I have a pregant cat she is roughly about 8 weeks pregant and showing no sings that the birth could be happening soon, I can feel the kittens moving around a lot, she isn't nesting or showing any kind of behaviour, I'm wondering how long left, what other signs should I look out for? Thank you

The normal gestational age for cats is about 65 days so you still have a few days left.  She won't start nesting until close to her birth time - this is an instinctive urge to avoid drawing predators to her nest.   We have several experts in pregnant cats and kittens on the forum and hopefully one will be along soon to give you some advice and answer your questions in more detail.  While you are waiting, read these threads for more info:

These and other useful articles are posted as stickies at the top of the Pregnant Cat and Kittens forum.   You might also read some of the threads in this forum posted by members whose cats have given birth.  They often describe the before, during and after stages and can teach you a lot.  Here are two, but there are lots of stories to read.
