It's kind of fucked up, but cats be cats after all. They can speak but I think they understand they are animals and pets and don't really question their place in society.
I mean, they do have lots and lots of privileges as pets and the sentient mind to truly enjoy being spoiled by their favorite humans.
Then again, while going to the vet is one thing... I don't want to imagine how it's for animal abusers. People that hurt animals for fun. It's horrible to think that right in this moment millions of kitties are suffering, yet in that world, that suffering is inflicted upon smart, sentient, human like feeling, precious little beings...
Let's just avoid thinking about it. For my mental sanity.
