My cat jumped in the dumpster and I'm planning to close the lid and leave.
Are you joking, why would you want to do something like that to your lovely cat?
I just don't love that cat anymore.
You need to take responsibility. You brought this cat into your home. Do right by it.
It's just a cat, I didn't hear it yelling at me.
If it is just a cat then give it to a pound, or give it away to someone, or just let it outside. There's no reason to torture a poor and innocent animal.
