Gamin is absolutely huge: One of his favourite sleeping spots is his indoor platform that's positioned right next to the viewing window, and you're left awe struck!
I bet one of them was Ivan; he was the last of the original 'Marwell Tigers' who died in 2007 after athritic problems, but he had a long life at Marwell and is probably most famous for accepting Zambar, the unrelated cub who was the son of his arch enemy Gamin, to live with him. For a while a few years ago whilst the tiger house was renovated and the two main enclosures were occupied by the breeding pair, Ivan resided in the old lion enclosure. It was a much smaller space, so you could realise just how massive he was.
