Unfortunately, my cat gives me hive. Or more specifically, his dander gives me hives. If it wasn’t for this product here. I wouldn’t be able to live with Otis. So for all of you cat owners or potential cat owners that are allergic to cat’s, might I recommend taking some zrtec to relieve your allergy symptoms. Amazon has some good deals and a huge selections of Zyrtec allergy medication so go there to see what they’ve got.
