what is the first thing I need to do after finding out my cat is pregnant? - The Waggin' Train Veterinary Clinic

Plan a visit to your veterinarian. Just a good physical exam will do, and then perhaps even taking a stool sample to check for intestinal worms. That is a problem that we will sometimes see with cat pregnancy. The hormonal changes that cats go through during pregnancy can cause them to begin to shed intestinal worms, even though they might've been negative before then. Those are good approaches to take when you first find out about cat pregnancy.
