I love my pets.  I have three cats.
I love cats, but my son is allergic so we can't have one.  What kind do you have?
Allergies are not fun at all!  I am allergic too but it is manageable with medication.  The cats are all rescues.  
What kinds of medications can you take for cat allergies?
I take an OTC.  Does your son sneeze and have a runny nose with the allergy or worse symptoms?
He does.  Itchy eyes, runny nose, little hives.  He just seems to get some discomfort in general.  He has the same things around Christmas trees :(
Aw, that's too bad.  Are you allergic, too?  Sometimes allergens are hereditary.
No, neither my wife or I are allergic, but my wife has a lot of allergies to other things.  We should take him to get him tested and find out what we could give him.  It would be fun to have Christmas morning with a real Christmas tree and a cat under it!
