USB adapter or cat deterrent?

According to a digitec user, a USB charger should whistle so terribly that cats immediately run away. Although this is not officially part of the scope of delivery, it gives me an idea. Our garden is a real cat paradise.

"This thing whistles like a marten trap. Our cat flees immediately when I plug in the USB adapter," writes digitec user Raffaele Carmine. His conclusion made it into our Community campaign. And because our Creation department, which is behind these posters, asked us if we would like to accompany the campaign thematically, I thought I'd quickly repurpose this adapter.

Go adapters, do your dirty business

I don't quite trust the peace yet. Does this adapter even work? Or does it really destroy your hearing? When I put my ear to it, I can't hear any whistling - regardless of whether one, two or no devices are connected. But that could also be because the sound is in a frequency range that is too high for my old ears.

I call in my eight-month-old daughter as an expert. I hold her face right in front of the adapter, but she does nothing of the sort. She reacts as she always does with new things: she tries to put them in her mouth. No response.

But not so terrible?

As a child, I wasn't allowed to have any consoles. It was only with the arrival of the family's 486 PC that the magical world of gaming opened up to me. Today, I'm overcompensating accordingly. Only a lack of time and money prevents me from trying out every game there is and decorating my shelf with rare retro consoles.
