Can a loud smoke alarm damage my cat's hearing? Is she deaf?

Updated on September 23rd, 2025

Over time can a Fire/Smoke alarm damage a cats hearing? She's not exposed it everday because It doesn't go off EVERY DAY, but Yesterday I did take a kinda steamy shower, and my smoke alarm went off. It took me about 10 minuets to get it go off, and my cat was in the room at the time. She's never had adverse effects before when it went off all the other times, but this time she seems to not act towards some sounds like she did before it went off. Is there a way to tell if shes deaf? even partly?

Loud noises can be painful to pets due to their sensitive hearing but it is unlikely to cause true deafness. The only way to definitely tell if she has hearing loss is through an electrical test called BAER test. This is only available at specialized universities and centers. It may be that she has just become accustomed to the loud noise and therefore does not have the same reaction as she used to.
