My previous cat very much liked the silicon rubber lead on my Weller WTCP iron.
She bit it in half, the cut from her sharp little teeth looking like it had been done with sidecutters!
When I was a kid, we were "off grid".
Our domestic radio was a large tube portable with two big flattish knobs on the top.
Our cat loved sleeping on top of it, & often, whilst moving around getting comfortable, would turn the volume up or down, or detune the thing, so we got used to weird sounds from the radio when she was around.
