sorry to read that you may not be getting the kittens now. There are so many OTC medications now for those allergic to pet dander. My son in law takes an allergy OTC pill before he comes to our house, with 7 cats, and it works. My husband was always allergic to cats, but now is not allergic to them. Is your son really allergic, or is it something else? Is is a shame for one to have to suffer for the other.,e specially if your son is not a frequent visitor to your home. Most people who are really allergic to cat dander have a hard time workign around people who have cats at all. Does he work in an allergy free work environment., just wondering....?
