If you live in an apartment, just don’t get one
Reasoning edit: pets, especially cats, will leave a smell all over furniture. Cleaning becomes an even worse chore due to the fur. They also require “house training” in order to not chew/claw/destroy most stuff that’s lying around the house.
I can assure you I can tell when I enter a house that has cats by smell alone, much like a smoker’s car has a distinctive smell
