I abandoned a cat I unwillingly adopted
Why would you abandon a cat?
I'm not used to cats and I don't like animals in general.
It's wrong to abandon a helpless animal. If you really didn't want it I'm sure you could find a place to rehome it.
Stories on the internet said it's basically impossible to find a place to give a cat to. I might as well just get rid of it.
It's fine if you don't like to have pets but still it was your cat so you should have put it on adoption or should have returned to an animal shelter. You should find your cat and do your duties as an owner.
