My daughters cat known as the galloping giraffe, he is very tall, lanky and very ungainly. He was lost for nearly three years and when he was found( due to his microchip) he was a bag of bones and would fall over trying to get up the stairs. He's been back a while now and eats nonstop, he has a 1st, 2nd, 3rd, 4th breakfast, lunch, tea, supper with the odd snack thrown in! And yes he is wormed and seen the vets about it, no health worries there.
