As someone who's had plenty of cat experience, I can say with relative certainty, not all cats would be like this.
Some might. But I have seen cats who get along with small animals, birds even.
One day my sister snuck home a random male cat she got on a farm figuring we'd get attached and she'd be allowed to keep it(didn't work out that way, apartment didn't allow cats at the time), it was a young but adult sized cat and pretty decent size for a cat. We had a small love bird with a mean temperament that was constantly escaping its cage. Cat tried checking out the bird, tentatively putting its paw out to touch the bird, trying to figure out what it was. This tiny bird so much smaller, bit the paw of the cat and chased it on foot!(wings were trimmed) This large size cat running away from a tiny bird, scared of this tiny bird, was a scene seen many a time before we could return the cat.
Had small toys designed for cats to chase, basically a fake mouse that goes around with wheels, a rather aggressive predatory wise cat got bored with it quickly. And never tried to eat it or throw it against the wall.
Cats have a excellent sense of smell, that is why with cats as well as dogs you offer your hand(with cats,you curl your fingers in so they don't think claws, is what one cat book said, but I've had it work with fingers extended), that way they can smell you and get to know you a little bit by knowing what you smell like. And I was visiting someone who had a cat who never let anyone else pet them except the owner, but because they were rolling around in the owners clothes and immersed in the owners scent, I was able to pet the cat. Shrunk people would still smell like themselves and cats do not simply immediately forget those who they bond with, and yes, they bond with people and other animals.

So yes, some cats might be aggressive and hurt their owners if they shrunk, we can't know for sure. But the author of this story clearly hasn't had alot of experience with different cats and their interactions with smaller creatures (that or just doesn't care, needs threats for the people to overcome or get horribly killed by) Walls of cats, some of which presumably recently fed, all trying desperately to get at the small humans, as shown in some pages like at the mall, completely unrealistic. Some cats are of a temperament that they simply don't go after small things much. Or only if the small things move in a certain way that triggers their predatory instinct. And cats again have good sense of smell, if it smells like a bird, they are more likely to go after it. If it smells like humans, even strangers to them, even though they be tiny, I think many cats would not necessarily attack, at least not immediately. Maybe eventually when they get desperately hungry that could be a different story. Though thirst would be the bigger issue.
