Cats and coughs

Years ago I knew a woman who had several cats even though one of her daughters was quite allergic to them.  I couldn't understand her point of view.  Later one of my daughters had a couple of cats and insisted that they , stay even though her husband said he was afraid of what they would do to the baby.  Eventually she reluctantly parted with the cats.  At present one of my granddaughters is suffering symptoms of asthma such as shortness of breath and coughing.  I suspected the two cats she lives with might have a relationship to her condition.  I arranged for her to spend most of the past few days and the night between at an Aunt's house.  She didn't take her usual allergy prescription and her condition seems much improved.  She loves her cats although she didn't have them until the family moved a few years ago.  One of them is getting very old and suffers pain from arthritis.  However the other is likely to live for several more years.  On the other hand several of my grandchildren are autistic and I believe I know a partial relief for their condition, but I am not their parent.  I have made mistakes in my parenting and likely some times I made similar decisions with the idea that I was doing the best thing for my child.
