Why is my cat still throwing up plastic and other things post-surgery?

Updated on September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | spayed | 5 lbs

I found a stray cat on Monday. My family took her in and she was eating but kept throwing up hours later. On Wednesday we took her in and they kept her overnight, did exploratory surgery (she had thrown up a piece of a plastic bag, but no blockage was found), they spayed her and found out she was 2 weeks pregnant. They did blood work, gave a dewormer, etc. She threw up another piece of a plastic bag and just now she threw up the attached picture. What did she throw up now?

I am not quite sure what she may have thrown up in the picture. It looks like it could be rice or even intestinal parasites. Since she is still vomiting parts of the plastic bag, I would be concerned that there may have been something missed during surgery. If she shredded the bag, there could be tiny pieces in her stomach and/or small intestines that would never be felt when look at these organs during exploratory surgery. She may need additional treatment to help these pass, including IV fluids, anti-nausea medications, enemas, or medications to help stimulate her intestines to move.
