I was diagnosed with gluten-intolerance about a year ago whilst at university. I also have IBS but most of the time if my diet is controlled I don't have many problems until I come home. Every time I come home for the holidays I start to feel ill in my parents house, I get bad stomach pains and have all the symptoms of IBS. This can happen within half an hour or being home and I don't even have to eat anything before it starts. The only thing I can think of is an allergy to cats. I also get a rash on my hands but don't seem to have any other symptoms such as sneezing. I've had cats nearly all my life until I moved away so surely I would know if I was allergic? Does anyone know if cats can cause stomach problems?!
