What are your "must-haves" to make my life easier as a cat owner?

Hello,

Would like to ask what are your must-have's to make my life easier as a cat owner? This isn't my first time taking care of cats but before, I used to own cats while working from home. I had a lot more time and was hands on with my previous cats but this time, my current cat is left at home alone. Most of the time, pagod na ako paguwi, but I have to do a lot of cleaning since whether wala or nasa bahay ako panay zoomies niya 😅

I'd appreciate if you can share stuff you've invested in as a busy fur parent. Links are welcome.

Here's a photo of my recently kapon cat.
