After watching some of the adorable videos on You Tube, I thought: Surely our BRILLIANT mixed Golden Retriever will quickly pick this up! HA! Yeah, she IS smart. Scary sometimes, but she also has ZERO interest in pleasing me. She acts as things like this & cute tricks are simply beneath her. But I had an even better use for them. I had taken in a pitiful, sickly stray cat & got him healthy. He USED to have a family, Vet said he has a chip. He called & theyweren't interested. (It still angers me!) I have no idea of his life before we met, but this rascal will NOT let me sleep. He's constantly waking me up, tapping my face, meowing, nibbling at me as soon as he sees my eyes close, like he's desperately trying to tell me something! I have awful insomnia, so if I'm awake reading or watching TV, he's ok. As soon as my eyes begin to get heavy, he's 6" from my face, tapping me awake! Oh, & he TOTALLY IGNORED the buttons too! So back in box they went. They're good as new & work great! I only used them 2 or 3 days. Each recording button takes 2 AAA batteries. Sorry, not included.
