Sorry it has taken so long to reply. I have been up since about 4 am, I opened all the windows to air the place out, Tony is allergic to dust. And its so hard to control dust in the winter time because the heat is always on and so on. I recleaned the air filters, and cleaned the ceiling fans, and he seems to be doing a lot better. I will still be taking him to the V-E-T so he can get his shot so his bumps will go away. I will keep you updated.
