I have had my cat who's about 4 years old for 3 years. In that time, I've always smoked in my place with the cat around. He would occasionally get the sniffles or sneeze and would always run the other way when I would light up (which was often). I started vaping a couple of days ago, and now he's started sneezing more often. I read somewhere that that could be an effect for me when I quit smoking, but I didn't realize that maybe the cat would go through "withdrawal". Or could it be that he's sensitive to the stuff that I'm vaping?
