Disabled Dude getting a cat

Hiya Folks,

I'm a 35 year old dude using a wheelchair due to being paralyzed, it's the first time in my life I'm living on my own after a breakup with the girlfriend and my siblings all moved far away. So I've been on my own for a year.

I decided I need a furr baby as a friend and companion.

I've never owned a cat before and I'm worried because I've had friends with cats and I don't know if I can handle a kitten on my own.

My major concern was the litter but I was super happy to find out about automatic litter robots ---- until I saw the prices!! are they actually worth it? I can't afford 1000$+ for a litter robot. Which ones are good for only one cat and provide automation?

anything else I should be aware of? tips and tricks to make my life easier?
