I just dropped my cats off at a shelter
Why would you do that?
I don't feel they respect me or my home.
Getting a pet is a long term commitment. Cats can live for more than 20 years if they are in good health and treated like family. Only adopt a pet that you are willing to commit too.
What do you think of me getting another cat?
If you just surrendered your pets you should not be looking to get new ones. I don't think you are fit to own pets, Maybe you can try fostering for a bit if you really insist.
