Hi Everyone.I have not posted in awhile.Nor answered many either.Health Anyways i am working with a lady who is dealing with Mega Colon.I belong to the yahoo group but have gone solo working with foreign country kitties which is in epidemic form.Here's the deal.Here in Canada royal Canin makes gastrointestinal High fiber Response dry catfood.purchased from vets only.It has been used for kitties with MC with very good results for most.I am helping a lady in the UK.Her link she sent me for the RC food does not have the same ingredients.Nor is the labelling the same.It basically says fiber formula on it.Knowing a lot about MC this can not be the wrong food or all H... will break loose.I am looking for anyone who may live in the Uk that may have used this product & the results.I called Rc here in Canada & they were clueless.It is made all over the world with different labelling & ingredients.I do not want her kitty to get bunged up being the wrong product.Also cisapride is not available to her as per our conversation.She is using emeprid(Reglan basically) or the same as Metoclopromide.Like comparing apples & oranges.Two totally different meds & actually meto is more for vomiting as it empties the stomach (Not well either) while cisapride starts stimulating nerves in small muscles right from the esophagus right down to the two sphincters kitties have.It won't be called cisapride there or anywhere close to there.It goes by many names.Any info would be greatly appreciated& hugs to all the babes.C
