How to tell if the stray cat I found is pregnant? What are the signs?

The signs you are describing certainly could be consistent with pregnancy, but Mia could also be suffering from a false pregnancy. This is when a cat shows the signs of being pregnant, but actually is not. The only way to know for sure if she is pregnant or not is to have her seen by a vet. I recommend giving a vet a call today to set up an appointment for her. Best of luck, I hope this helps!

She very well may be pregnant. Her belly does look abnormally big there. Watch for signs of pregnancy such as mammary gland engorgement, continued weight gain, increase in appetite. Also you can have her seen by your vet for an exam to check for fetal heartbeats or to identify the fetal skulls, via radiograph (as early as 45 days gestation). If she is suspected to be pregnant then it's also best to feed her kitten food which is going to satisfy her high calorie requirements and ensure she makes a good supply of milk for her kittens. Best of luck with Flash. I hope everything works out well for you both.

From these pictures it does appear that Coco’s abdomen is slightly distended. However, there can be many other reasons for abdominal distention such as fluid in the belly, heart disease, false pregnancy and/or intestinal parasites. My best recommendation would be to take Coco in the vet to be examined. This would give you a better idea of her overall health and they may be able to determine if she is pregnant. I hope this helps. Thanks for using Petco Pet Education Center, formerly Petcoach. Best of luck.

Check if she has milk in one or more of her teats. If so, it is possible she has kittens. When she comes to eat, catch her and take her to your vet for an exam. and then let her go again so she can go feed her kittens. She may have another problelm with her abdomen or she may have retained a kitten. So this is serious.

Have her physically examined y a veterinarian. An abdominal ultrasound should be able to confirm a pregnancy. At this stage, if she is pregnant, her nipples should be enlarged and darker and she should be putting on weight. It is possible for her to still be active.

Thanks for using Petco Pet Education Center, formerly Petcoach! Mia does look like her abdomen is mildly distended, which may be due to pregnancy, or may be secondary to another underlying issue (fluid accumulation, etc.). If she is pregnant and her expected due date is in 2-3 weeks, an xray can verify pregnancy, as well as count how many kittens (if any) she is going to have (and sometimes kittens can be felt on physical examination). I would recommend having her evaluated by your regular veterinarian to determine if she is pregnant or if she has another underlying issue that needs to be addressed. Good luck!

"Mama" is a very pretty girl! :) I agree that her abdomen definitely looks enlarged. It's possible that she could be pregnant, but the enlarged belly could also be caused by something else such as an abdominal tumor, heart or liver disease, or FIP (feline infectious peritonitis). Cats are only pregnant for 64 days on average, so if her belly has been swollen like this for more than a few weeks or so, I would be very concerned that something else is wrong. The best way to find out would be to take her to the vet for an exam - he/she can palpate her abdomen and may also recommend x-rays or ultrasound to help determine for sure what's going on.
