How do you handle separation anxiety from leaving your cats for a long period of time? week to weeks

My friend got an interactive thingamajig. It's connected to Wi-Fi, it has a camera that moves, it has a toy hanging off the top that's connected to the camera, and it can dispense treats. It also has a microphone and a speaker, so you can talk to and hear the kitties. That seemed pretty neat

I have gradually set up cameras all throughout my home so that I can peek in on them whenever I feel like it. I also just avoid leaving for extended periods and/or drag them along with me.

We have an RV and usually bring them with us, which generates its own set of issues, but at least we're not missing them!

Of course that doesn't work for trips abroad, so we hired a company to come in daily and take care of them while we were gone. They sent us pictures and updates!

I have a hard time leaving my two (we have way more, but only two are mine) for the day when i go to work. I also have one that lives at work and i have a hard time leaving her when i go home for the night.
