Pet's info: Cat | Mixed Breed | Female | spayed | 6 years and 1 month old | 15 lbs
My 6-yr old cat has been getting sick for about a week every 4-6 weeks. She starts throwing up a few times a day for a few days. Then she throws up a pink liquid only. Then she has diarrhea sometimes with a red mucous. And sometimes she's constipated. My vet says there's nothing wrong with her. A 2nd vet thought she might have a food allergy. Any ghoughts?

Certainly mild to moderate food allergies can be the cause of intermittent GI disease, however Shirley's signs seem a bit more serious that what I typically see what food allergies. I hope that you have considered blood work and imaging (x-rays, ultrasound) of the abdomen, because you need to also consider whether this could be due to an intermittent blockage in the stomach or intestines due to a foreign body. Before you consider a diet change to test for food allergies I would want to be sure you have ruled out more serious problems.
