On April 7, 2011, Mark Kroll of Crystal Bay, Minnesota patented a 'Domestic Animal Telephone.'
A large number of individuals have mammalian pets in their homes. These are typically dogs or cats. When the pet owners are away at work they often would like to communicate with their pets. Similarly, the pets often would like to communicate with their owner.(via Look At This...)The Presurfer
The gist of this invention is a practical telephone for mammalian pets. The phone could either 'be called by a human from a remote location in such a way that the animal can answer the phone.' Alternately, 'the pet can initiate the phone call.'
