Hi. I have a female cat, about three years old, not spayed, never had a litter who recently mated with my neutered cat. About two days later there was a yellowish discharge from the female cat. The vet prescribed antibiotics which only temporary cleared it up. After several prescription refills it still hasn't cleared up and I'm wondering if the bacteria is becoming resistant to the antibiotics. The vet will not change antibiotics saying that the right one was prescribed. The closest thing I can come across to what it is is Trichomonas vaginalis although there is no odor. The discharge is a creamy pale yellow with a greenish tinge. Quite copious at times. She is in good health otherwise. Is there a homeopathic, safe for cats, that will correct this? Thank you for any info.
