I am allergic to cats.
Have been since I was a child.
My face/eyes, swell up. And I itch like crazy.
It is not, fun.
At, all.
Oh, and then I have had Asthma too... since I was a child.
So that in combination with cats, is not fun, either.
IF I have CONTACT with a cat, my body/allergy reacts.
Common sense. If the dander/fur/anywhere a cat goes, is on furniture or other places too, I react.
And, with cats in a home, it is IMPOSSIBLE, to clean a home daily, of any fur/shedded fur or dander, that is in a home.
And no, there is nothing to spray EVERYWHERE in the house, to get rid of cat, dander or fur.
Your Step Daughter's Mom, wants you to get rid of the cats.
This is her, daughter. And she is concerned about her daughter's health.
This is natural.
Sure, your Step-Daughter can take meds.
But that is up to her parents.
But she will still be, allergic to cats.
Sure she can go to your house. But you have cats. And she is allergic to cats.
How old, is your Step Daughter?
Or, keep your cats, outdoors. Have them as outdoor pets.
But your Step Daughter, cannot touch them.
Bendaryl... causes drowsiness.
Do you want your step daughter, to be drowsy, while at your house????
Does her Mom know, that she is being given, Benadryl????
You need to ask the Mom, first.
The cat allergy can potentially become worse.
I would ALSO, get an air purifier for your home, for all the rooms.
But this still will not get rid of, her allergies. But it may help with the air quality in your home.
And, any carpet you have, the cat fur and dander... will saturate it. Thus, it WILL affect her allergies.
Now, when I was OLDER and in college... I had pet cats. BUT they were outdoor cats. AND, by that age, I KNEW to wash my hands/clothes immediately after playing with them. But you cannot compare cat allergies to others, because each person will react... differently and per severity.
