If anyone has a pet that likes to wander off then you should try the Kipayment Evo! It is an amazing little device that can track and show you where your pet is. It has GPS and you can see where they are on the app for it. It also shows you the pet's activity and is a fantastic app. You can turn on the light that is on the device which is attached to the dog's/cat's collar by a velcro strap though the app and set a timer for it to go off so you can see your pet easily to. The basic package is £7.99 a month but is well worth it for peace of mind. It is waterproof to and it has helped motivate my children to walk their dog with me as they enjoy seeing the dog's activity on the app. Definitely worth a buy!
