Miss Kat was in the bathtub today and something crazy happened. I dropped the toilet seat closed and Miss Kat startled. I was surprised, so I did it several times (with the shower curtain closed, so no peeking) and she pinpointed every time.
The sound wasn't very loud, so I was very surprised. I know that she still had a little hearing left, especially in the low frequencies but this was way less than 80 db.
***SHE said she heard it, not me. She told me that it was a THUMP and imitated the sound and said it was loud.***
