I think this is what you meant to post?
I'm all for killing every single feline on the planet to save our human race asap, but not dogs. Dogs have learned over the years through trial and error to prevent their gases from damaging the environment. Cats on the other hand continually just spew out there shit. What's worse is people have them do it on purpose in litter boxes, combining with the kitty litter and forming deadly chlorine gas! ALL felines must be destroyed, humanely or not, if we are to continue as a species.
