My cat Blue is pregnant with her third litter and she has a greenish-yellow discharge coming from her vagina. I do know that her mother had chlamydia and we treated her with medication given to us by the vet. Right now, we are in a tough spot and cannot afford to take her to the vet, so I was hoping that there was a way to treat it at home without expensive medications. If anyone knows of a way to treat chlamydia at home, please let me know. My mom believes that it could possibly be her muscus plug coming out in small bits but it started on June 14th, Thursday of last week and today is Tuesday and she's not really showing any signs of being in labor. After this litter, we are planning on getting her spayed and our male altered so we don't have anymore kittens.
