My brother brought home a stray about 2 weeks ago, and we're beginning to wonder if she's pregnant. Her nipples are large and pink and the fur has fallen off. She's also eating like a pig (even stealing my cat's food). We have a vet appointment for next week, but are not sure what to do until then. Her belly seems very sensitive (she hisses and runs whenever we touch it), and she keeps finding hiding places. She doesn't look huge or anything, but I'm not an expert on cat pregnancy. she was also pretty underweight when we got her (she looked to be about 6 months old), so that may have something to do with her not looking too big. She's just now regained a "normal" cat figure. There also isn't a visible tummy scar, so I doubt she's been spayed. Could she be pregnant? What can we do to make things easier for her?
