Do houses with cats and dogs usually smell?

I will admit, I could just be paranoid and overthinking this situation (which is why I'm asking here).

Do houses with cats and dogs usually smell?

I just went to a private showing of a property that did have a cat in the house while my realtor showed me around. During the private showing, the entire house smelled like air freshner. The basement was the only place that didn't smell of air freshner.

Only reason I ask is because I've seen horror stories on this subreddit where folks talk about how the open house was amazing and the house smelled fresh, only to realize that the owner was using the air freshener as a cover up.

Not to mention in the backyard, the house did have a lot of dog poop in certain spots. That was a bit of a red flag for me. If your going to show your property, one would assume the homeowners would clean their backyard of dog 💩 to appeal to buyers?

Thoughts?
