It was me, I just found the article again.It was by vet Richard Allport who writes for Cat World. He was commenting on a lecture of the European Society of Feline Medicine/British Small Animal Veterinary Assoication Symposium on FLUTD (Feline LOwer Urinary Tract Disease) (bit of a mouthful, LOL!) This particular lecture was given by two UK cat experts (doesnt say who) and the jist is FLUTD is a collection of conditions, many cases are idiopathic (no known cause). However, there are some factors known to predispose to getting the condition - being persian, being black and white shorthaired and being overweight. Also that autumn and early spring were peak times for symptoms. Thats all it said about those factors, doesnt say why in this article, but perhaps in the original lecture it did.
Theres more to the article, I can photocopy it for you if you'd like? I'm not sure of the date of it as I tore it out of a cat world mag and there's no year at the bottom of the page, and since I've been getting CW for years, it could be a couple or more years old!
