Help!!

My mother cat had her litter 9 weeks ago and tonight she gave out a small amount of discharge which was brown red almost black and it was quite smelly should I take her to the vet first thing in the morning or am I stressing? Please advice is needed..

I would at least call them.
 

I would.

its been 9 days how did things turn out? Did you find the cause and the treatment for it? Just curiousm. Hoping for the best
