This is an undemanding book about how Cats Are Good, with a rather charming premise: people who are struggling in their lives (in minor ways: irritating co-workers, uncongenial jobs, difficulties connecting with their children) somehow find their way to a psychiatric clinic in a building that isn't always there, where an odd doctor gives them a cat as a prescription. It's cute. It's pretty obvious. There's a little bit of a mystery about the nature of the clinic that is resolved in a sweet but not terribly surprising way. This would be a good book for someone who is grieving the loss of a beloved cat, perhaps; but there's not much else to it.
