Does anyone know what affect this has on a cat, smoking around them? I would like to convince the bf about this but I have not been able to find enough info to prove that it has an affect. I am sure that it cannot be good for him at all. Obviously I would prefer that the house was none smoking, I know if bf thought that it was having a negative impact on Al, he would stop. Does it affect them as it would us humans? Also my kitty had a uri a while ago so would that be an added issue? Thanks if anyone can advise.
