"A cat with sore joints still eats and purrs. He just stops jumping onto the windowsill."— Dr. Kim
Most problems owners bring to the vet began weeks or months earlier. The cat was sending signals; no one knew how to read them. A few examples from the book:
What it may mean: sore joints. Cats with arthritis rarely limp. In one study arthritis was found in 82% of cats over 14, yet limping was noticed in only 13 out of 100.
What it may mean: in cats over 8, a sudden rise in attention-seeking can be an early sign of hyperthyroidism or cognitive changes.
What it may mean: cats also purr when stressed, in pain or seriously ill, probably to calm themselves. A purr isn't proof that all is well.
What it may mean: stepping over the rim hurts, or an aversion to the box has already formed. Punishing him only teaches him to hide.
What it may mean: possible kidney disease, diabetes or hyperthyroidism. Clump size is a free daily check you already have.
What it may mean: chronic stress and illness rarely look dramatic in cats. More often it's a slow fade of his usual behavior.
From the book's "When to see the vet" sections. This list is not complete: if something feels wrong, call your vet.
Every chapter ends with a myth and the fact behind it. Tap a card to flip it.
Each of the 34 situations follows the same short, clear path, so you can find your answer in a couple of minutes.
Walking across the bed, pawing at you, knocking things over, meowing. Most often, he expects you to get up and feed him.
From the night shift to the litter box, from the tail to the teeth. Here is the full list.

Plus a starting chapter: when to see a veterinarian today, and red-flag lists in almost every situation.
Heart disease often causes no visible symptoms early on. Hypertrophic cardiomyopathy affects roughly one cat in seven, and a gradual rise in sleeping breathing rate can be its first measurable sign.
At the clinic a cat is tense, so the most accurate number is the one you count at home while he's in deep sleep. Count the rises of his chest for 30 seconds, then double it.
Record it weekly: the trend matters more than any single number.

Wait until your cat is in deep sleep, not purring or just dozing off. Press start, then tap once for each rise of the chest. You can also press the space bar.
