They grow quick. Marvin was the same, looked like he was going to be a monster size cat but it turns out he's not (he's 3 now (already <eek>)).Also, he’s nearly 2.5 kg and not even four months old. Bruiser cat.
Mr Best is the heaviest of our lot but he's in the best physical shape of them all (years of being homeless probably) - he's just solid all over and has the strongest neck I've ever known of any cat.
