Nasal Allergies

This blog has not been updated for past couple days because both Minna and I have been suffering from nasal allergies since Sunday. I have already ruled out the catnip plant we bought on Saturday, it is either the feline pine cat litter I bought on Friday or other allergen from outdoor. Since we only live two blocks away from Yerba Buena Gardens, it could be pollen trees and weeds.
I am planning to test Feline Pine and Nature's Miracle Cat litter, will post my result in several weeks.
