DH used to smoke a lot. So I expect it was a sort of back ground smell. I smoke, not as frequently as he did. When I light up now, MCat isn't bothered, he was with DH from a kitten. However Little M jumps off my lap and glares at me.
Is second hand smoke harmful to cats, I'm wondering. Might have to give up, or at least start smoking outside, or invest in a vaper. (I had a couple but lost them.)
On the upside, my cigarette use has reduced considerably. Downside - pleasure of smoking is cancelled out by guilt.
