I don't know of a problem with cf and cats either. I have had animals my whole life ( dogs, cats, birds, reptiles, rodents) and not once was i ever told to get rid of any of them. I never had a problem with any of them, but as Debbie said, i also grew "into" having alergies. I am allergic to dogs, cats, trees, grass, mold, dust....this ,that and the other thing like everyone else. I take "Zyrtec" and it does help. The only problem i have with dogs and cats is.. if i pet them and rub my eyes, other than that its fine. I currenty live with 8 iguanas, 1 skink, and 2 cats <-- had them for 14 years. Maybe you could get an air purifier. It would be a shame to take an animal away from a child that loves him.... unless there was an obvious serious problem. And the playground sandbox problem.... oh gosh i am not proud of this, but when my friends and i were kids and played in a sand box, we found some "buried treasures" and never washed our hands afterwards. Kids rarely understand the importance of handwashing. The only thing you can do is try to make it a routine to wash the hands whenever they come in.
