You did the right thing. How allergic are the folks in your house? Mildly or severe? If they are mild allergies being exposed to cats could desensitise them over time...It won't be easy but can be done. I used to be allergic. Now I own four cats! I must be nuts.
They're pretty allergic. Nuts is under-rated. I know no-one normal. Nuts is the new black :)
