There are several symptoms of a cat miscarriage:
- Vaginal discharge: Usually cats do not experience vaginal discharge when they are pregnant. Therefore, if you do notice any sort of yellowish discharge - which could be either thick or runny - from your pregnant pet, then take her to the vet immediately. Any fluid coming from the vagina of your cat that isn't urine should be considered to be vaginal discharge.
- Fever and not eating: If a pregnant cat experiences a noticeable increase in temperature, and is therefore inactive and panting, then this could be a sign of miscarriage. Loss of appetite is usually associated with a high temperature.
- Fetus removal: You may find the miscarried fetus of a kitten around your house or in your garden. Usually this will look like a bloody sack, but it could resemble a kitten, depending on how pregnant your cat was.
