The queen will produce more of the pregnancy hormone called progesterone, which makes her body think she’s pregnant.Signs of False Pregnancy in CatsThe signs of a false pregnancy are similar to a queen that is actually pregnant. This often makes it quite difficult to diagnose a false pregnancy. Symptoms you might notice include:Enlarged mammary glands and nipplesIncreased appetite and/or weight gainBehavioral changes such as finding new places to sleep/nest, and changes in attitude such as becoming less affectionate and less activeRead more about cats and pregnancy here!Diagnosing False Pregnancy in CatsAs mentioned above, it is difficult to diagnose a false pregnancy in queens. However, your vet can determine if your cat is pregnant using ultrasound from day 28 of pregnancy or by x-ray after day 45 of pregnancy.Treatment Options for False Pregnancy in CatsTreatment for queens experiencing false pregnancy is usually not needed. The signs will typically resolve without any treatment and the queen will come into heat or be ready to mate again 6-8 weeks after the last heat cycle. For breeding queens that experience a false pregnancy, sterilization or spaying is strongly recommended.Increased circulation of progesterone in unspayed queens can lead to a serious life-threatening condition called pyometra. Pyometra is an infection of the uterus. The uterus fills with bacteria and fluid which can lead to death if left untreated.Treatment of pyometra involves hospitalization for supportive care including antibiotics, pain management, intravenous (IV) fluid therapy and sterilization surgery to remove the infected uterus.Preventing False Pregnancy in CatsIdeally, schedule your female cat to be sterilized between 4-5 months of age, or as soon as possible once you adopt her.
