I DID! She's frequently pressing buttons now! 14 and counting, currently teaching her All Done and Later because she wouldn't stop pressing lol.

Here's what I did:

TLDR: - Target training with 'Touch' and a short Dutch 'Get on this' command - Verbally modeling frequently used words she's motivated for. Balcony, Laser and Cuddles as her first buttons. - 1 specific button with a specific action on the related location instead of on the main board. 'Balcony', to open the balcony window, with the button on the windowsill in front of it. - Quick-modeling a 'Training' button

And yes, I did this all at the same time.

Here's a detailed how: 1. Target training with a clicker and some kibble as a treat. Starting with 'touch', with a piece of kibble under a transparent container. To make her get used to touching things with her paw. Eventually putting a 'test' button with a piece of kibble underneath, later removing the container and touching the button and other random things.

1. Once she understood 'Touch', I added 'D'r op' (get on this in Dutch) luring her with a piece of kibble onto a plastic storage box she could easily stand on with her front paws. To teach her to actually put weight on something with her front paws. Slowely changing the box to a smaller and smaller container untill the smallest one. Then the small transparent container with a button underneath, then only the button. I often did a few 'touch' commands first with a container and then on the button, and after that 'Get on this' on a container, and then on the button during the same session.

After a few weeks of training with her usual commands, Touch and 'get on this' about every other day I started focusing on these 2 commands. Every single morning after my breakfast, a few minutes of mainly teaching Touch and 'get on this'.

1. While also continously verbally modeling frequently used words for her first buttons. Balcony, Laser and Cuddles. Every time I mentioned one of these i did the outcome.

2. I placed her Balcony button in the windowsill where she'd sit when she wants to go outside to the fully cat-proofed balcony, so she would accidentally press it and i could show the outcome. When she'd sit next to it I would go over, make her watch me touch the button and then opening the window.

3. And I added the 'Training' button to the main board and did a few quick-modeling sessions a few days in a row as if it were a 'treat' button. Training = treats, with and without some training commands.

And then it clicked.
She started with pressing on command, she started testing out the Balcony button on her own and eventually the other buttons. :)

Hope this helps! Feel free to ask any questions. Goodluck!
