You know those automatic air fresheners that respond to movement? Don’t have them if you have an animal. My friend had one and when it went off it made a noise like a hissing cat! Her cat used to walk past, it would go off…and the cat would hiss back at the air freshener and would look around, looking for the other cat! I couldn’t help but laugh at that, and every time I see an advert (like I did a few minutes ago) it reminds of that!
