Here's why:
* Other reasons for enlarged nipples: Nipples can enlarge due to hormonal fluctuations, even if the cat isn't pregnant. This can happen during heat cycles, for example.
* Other pregnancy signs: You'll need to look for other signs of pregnancy, such as:
* Weight gain: A gradual weight gain, especially around the abdomen, is a common sign.
* Changes in appetite: Some cats eat more during pregnancy.
* Nesting behavior: Cats may start to collect blankets, toys, or other items for a nest.
* Abdominal swelling: The belly will become larger and rounder as the kittens grow.
* Pink discharge: A pink or clear discharge from the vulva may occur towards the end of pregnancy.
To confirm pregnancy, the best thing to do is:
* Take your cat to the vet: A veterinarian can perform a physical exam, palpate the abdomen, and potentially do an ultrasound to confirm pregnancy.
It's important to remember that even if a cat is pregnant, not all of these signs will be present. Always consult a veterinarian for a definitive diagnosis.
