If you have an obsession for a particular type of animal, now you can hear your favorite one every single time someone rings your doorbell. Be it a horse, cat or dog, you can either hear the voice of that particular animal or program it to have a different chime. You can also get a Lark doorbell that plays the “sounds of nature” and a dolphin shaped one that plays “Pour Elise”. The cat doorbell would be especially fun to drive your dog insane if they have a particularly strong hatred towards cats. The doorbells range in price from $10.99 on up to $11.99 from Sourcing Map. Purchase with caution though, some of the plug-in doorbells have German plugs, so those with an average US outlet could have issues.
