Play With Your Cat! is full of excellent advice for anyone who has a cat and wants to engage with them more through play (which honestly should be everyone who owns a cat - having a cat in your life should mean that playing with them comes with the territory, much like having a dog means you need to be out walking with them!) Delgado goes through the (somewhat lacking) science, busting myths like "some cats aren't playful," and "cats are aloof and don't like people."
While it took me a bit to get through, Play With Your Cat! is honestly a fairly quick read. I recommend it for all the cat lovers out there who want to learn more about strengthening their bond with their cats through play!
