This is the first thing that has worked in any tangible way in 3 years of suffering with really severe cat allergies that hindered my ability to work. Like many others I too threw the whole kitchen sink at the problem to no avail, using HEPA filters, trying every otc allergy med, etc, with at very minimal improvement at best, not nearly enough. I reapply every 2 days at the least or more if necessary and this seems to keep the allergies at bay, finally. The cat hair in my place is inescapable— it floats about even with regular cleaning and manages to get in my facial hair and mouth sometimes, exacerbating the problem. I think the combination of food toppers and spray work well together and maybe are both necessary to get full coverage and relief. Plus, the cat likes me even more now that I’m adding the topper to his bowl (a double edged sword, now he wants more love and attention from me)— I add in some Flonase or Claritin for myself for consistency and other allergies, and things are back to normal again— and I can coexist with my roommate’s great cat. Well worth it!
