Sneaky way to uncover pets? smoking?

[Ken Latchers]

I was wondering. As many tenants will tell you to your face that they do not have a cat or dog, and then try to sneak them in...

What about the following idea: Ad text say "pet friendly" Seems people are more likely to reveal pet ownership that if you say "no dogs/cats allowed."

And wondering the same for smokers. "smoker friendly"

As it is not illegal to discriminate against pets or smokers...

Thoughts?
