PeTalk is the portable machine that lets you record up to a 10 second message for your pet, then allows you set the frequency of playback, as often as once per hour. Hearing your voice while you're away will comfort your pet when they're left home alone, when they're in a kennel, or at the vet's recovering from surgery. It measures just 3.5"W x 2.5"H so it's perfect to hang on crates or kennels. Requires 4 "AAA" batteries (not included).
