My cat is 66 days pregnant.
Her due date was Friday, and she is still not showing any signs apart from, nesting and sleeping a lot. She is eating normal, and her belly had gone hard which is meant to be a sign that she is close. Her temperature went down about five days ago to 96f. But keeps going up and down, is this normal?
Also we think she might have lost her mucus plug, as she lost a clump of gooey white discharge and then some bloody watery discharge. She keeps stooping and crouching down as she walks, and seems to be concentrating on something, is this the contractions and she is just in slow labour? Just worried she might need help such as a c-section. Any advice would be much appreciated

Here is some information for you.

Are you certain about the length of pregnancy?
Typical gestation period is 64-66 days. So you were right to start watching her when you did.
If she has not gone into labor by the time your vet opens up tomorrow it would be a good idea to give them a call, they may feel the need to examine her to make sure that all is well.
