Many thanks for the help and advice you gave me at the National Pet Show in Birmingham yesterday. My 6 month old kitten, Ernie was not dealing well with his first exposure to fireworks. Within an hour of putting in the plug-in, last night, Ernie was much more relaxed and calm, sleeping through the fireworks which still were being let off late last night. He was so content that he fell asleep in his play box on top of his fleecy blanket. Many thanks. I will certainly recommend this product to other owners and top up my plug in as and when required.
