The soothing music on this iPhone app is designed to calm down nervous kitties. It’s essential if you have a cat that gets stressed out during trips to the vet or during house moves. It’s also ideal if your cat is feeling a bit hyperactive and is racing around your house in the middle of the night. Like the Pet First Aid app we mentioned in our post about dog friendly apps, this entry is a bit of a cheat as it’s not just for cats. Pet Acoustics also includes music designed to calm down dogs: and horses!
