Methods: Population based case-control study with 136 clinically definite MS cases and 272 controls randomly chosen from the community matched on sex and age. Data was collected from both questionnaire and a lifetime calendar detailing residence, occupation and pet/animal exposure over the course of participant's lives.
Results: Exposure to farming, livestock, specific farm animals and remoteness of residence showed no significant association with MS risk. Exposure to cats prior to disease onset was associated with a greater risk of MS (Adjusted Odds Ratio 2.46 (1.17–5.18)) but without a clear dose-response (test for trend, p=0.76).
Conclusions: In contrast to other literature, farming and exposure to farm animals were not associated with MS. While we identified an association between cat exposure and MS, there was no dose-response relationship, and previous studies showed inconsistent results, leaving us to conclude that there is no strong evidence that exposure to cats is associated with MS.
