Not really sure what the point of this post is honestly. Are you just venting? If you really feel this way about having to clean up after your cat, maybe having a cat just isn't for you?
Pets are a responsibility, and there are aspects of that that suck, but we put up with it for the parts that are good. If you feel like it's too much hassle that's fine, but it means you shouldn't own a cat since you're not meeting its needs. Someone that felt it was too much of a hassle to walk their dog and clean up after it likewise shouldn't own one.
Edit: Also if you do decide that owning a cat is too much for you PLEASE do not just dump it somewhere. Ideally you'd find a loving home to adopt it, but at least turn it over to an animal shelter.
