Yeah it was amazing the difference! The first time I saw him he looked pitiful and he was miserable. Then a little more than a month later ( maybe two), he was doing so much better. He's so funny. He loves this little ball with a bell inside. You can hear him through out the house playing. Also at night time, he sucks the pad of his paw and I am dead serious, he makes the loudest sucking sound. It sounds like a toddler sucking on a passifier.
