I'm thinking of giving up my cat for adoption
Why do you want to give your cat up for adoption?
I can't care more than I do.
If you don't care anymore than you should give it up for adoption. It's better than having it raised in a loveless environment.
I'm raising it in a loveless environment because my parents hate cats.
Giving your cat up for adoption when you can no longer take care of it is a responsible choice. It's best to place your pet in a better environment.
