Cats and typewriters

This series of videos explore the relationship of cats and typewriters.
I know you're used to seeing videos of cats doing funny things, but my cat doesn't like typewriters.
He ignores them, looks at them a bit to make me happy, but eventually he leaves as soon as he can.
It's very frustrating.
I'd love to share my passion for typewriters with him, but he ignores me.

In these videos there is the demonstration that my cat doesn't like typewriters.
I tried with a lot of typewriters with the same result.

1) My cat doesn't like typewriters: Aritmomemter Payen P3A (1897), Hammond Multiplex (1913), Frolio 7 (1924), Blickensderfer (1910)

2) My cat doesn't like typewriters, and also calculators, AEG Mignon (1925), ThaleS Rechenmachine, Royal Bar-Lock (1909), Duconta calculator (Ducati Motors 1940s), Underwood 22.

3) Still my cat doesn't like typewriters: Olvier 9, Olivetti MP1, Urania 7, Olivetti M20, Torpedo, Lilliput.

4) My cat doesn't like typewriters, and not even their photos in the catalogues

5) My cat doesn't care when I try to explain him how to do square roots with a mechanical calculator

Goodbye Puff, it was wonderful spending so many years with you, and I'm grateful for that.
You filled my days with your joy and affection.
I hope to see you again one day, on the other side.
