Thanks everyone, really touching.
He was the little one of what was once a trio, a special little chap. We sadly had to separate them due to fighting, tried reintroducing them on a couple of occasions but to no avail. At the time of his death, we were in the process of finding him a friend. Sadly, overnight he suddenly had breathing difficulties and passed away in my mum's arms before we had chance to take him to the vets. His final resting place is by the plum tree. Miss him dearly xx
