possible pregnant cat. Please help!

Please some one help us. Our cat may look like she is pregnant. Her nipples look swollen and her tummy is a little hard. She is such a tiny cat that I really can't tell if she is.

Sounds and look pregnant to me

The vet will be able to confirm it

My husband and I think so too! Getting her to the vet is difficult with our demanding jobs and schedule. I wish I could take her now!!

Stole the links again from our advisors haha
