My pregnant cat.

Hello. My cat is 4 weeks pregnant and today she came in a little unsettle and keeps getting lots of discharge that she keeps cleaning away.
Does anyone know why this is? Just worried as she's 4 weeks gone so don't think she's ready for it to be labour.
Thanks.

You might want to call your vet and see if that is normal, be ready to describe what is going on in detail, color, amount, and whether clear or cloudy. Tell them she would be too traumatized to bring in, I think she would be.Maybe look it up on the internet. I hope someone can answer you with more expertise then me. Good luck! 

Thank you.
She doesn't seem in any pain, and is eating and sleeping still. All I can find on internet is about labour. I don't know if this is what it is as she's only 4 weeks.
I'll phone my vets.
