What should I do if I notice my cat's spine sticking out?

Oh, dude, if you see your cat's spine sticking out, you should probably take a break from petting them so aggressively. Like, maybe dial down the intensity of those back scratches. But seriously, if your cat's spine is visibly protruding, it's definitely time to take them to the vet for a check-up. Like, cats aren't supposed to have a bony ridge down their back, so that's a sign something's not right.
