You have to do whats best for you and your kittyI actually just threw away my rugs and cleaned my hardwood floors today. I'l keep doing it everyday. As far as the walls i'm not going to paint it or wash it as its not a easy thing to do as I would have to move everything around. I'm moving out to my families basement while i rent out my place. Its a smoke free place. If you think i should go ahead and clean it then I would but its only for 2 month here. My apartment is not as bad as other who smoked for 30 years. Ive been a smoker for only 3 years and I quit 3 months before I got my cat. Either way i heard those particles from third handing smoking lasts a very long time like years. I'm also leaving the my place furnished for the renter so I wont be bringing back any smoked infested furniture. The only thing Il be bringing is my computer chair and my clothes.
As far as daily life goes I have friends who smoke. They wont smoke in my new apartment but they would come in smelling like smoke. I really dont know what to do. I cant shield away from people to much.
