Thanks everyone.
My husband will not go with my son unless it is only to the GP Daisycat. Yes he does have a spacer and uses it, but only occasionally.
I had not thought of getting a nebuliser to keep at home tsn, so far he has only had to have one once, that was the first time he started gasping/ wheezing.He has managed with the inhalers since then. I must admit I would have a problem getting rid of the cats as we have had them for years, but I will definately suggest his carpet goes.
I have just looked up Buteyko on the web and I may suggest he looks at that some more.
Thanks to all for the advice.
