I recently found this set of four photos in which someone was documenting their cat’s obsession with the television. No date/info.
@CatsOfYore I see a cat with much more sensitive ears than ours hearing some electronic component inside the TV make a sound too quiet or high-pitched for human ears.
@dancingtreefrog @CatsOfYore that brings back memories. When I was a kid, we'd visit my grandmother and her TV had this terrible high pitch ringing that I hated so much. She probably didn't notice it at her age but my kid ears surely did!
@meanderingok @CatsOfYore We were watching a video tape many decades ago - myself, my spouse, two adult friends, and their two children. The children kept complaining about a high-pitched whining sound none of us adults could hear. The sounds stopped when we turned off the VHS player...
@dancingtreefrog @CatsOfYore yep that was the sound!

@meanderingok @CatsOfYore It didn't stop when we stopped the tape, either, so I think it was coming from some electronic component inside. Maybe a dying capacitor or such in the sound circuit somewhere.

We dumped the VHS player and have been replacing the old commercial tapes with DVDs ever since.

We have two tapes our daughter made during high school, so we'll eventually need to have them digitized, I suppose. There are services that can do conversions.
