Reddit mentions of Handy Gourmet Set Of 3 Pop Up Food Covers

There's a motion-activated compressed air device that we've used to deter our cat from certain areas: https://www.amazon.com/PetSafe-Deterrent-Activated-Repellent-Environmentally/dp/B0721735K9

For new plants, especially small babies or props, we cover them with a mesh food cover to discourage nibbling until we're confident the cats will leave the plants alone. These may not work for a taller, upright plant like a Ponytail Palm though. Or a very determined cat. But it's been effective for our needs.

Here's some different types:

• Large Mesh: https://www.amazon.com/dp/B07FDV517W/
  
• Pop-Up: https://www.amazon.com/dp/B000EYFV4M/
  
• Mesh & Bamboo: https://www.amazon.com/Cocoboo-Serving-Natural-Artisan-Handmade/
  
  For more desperate measures when we needed to keep cats off window sills or ledges, we put some wide double sided tape on the window sill or some kind of sticky or noisy pad they wouldn't want to walk over. There's all kinds of "cat training tape" or scratch control strips for furniture available online or at pet stores.
