It sounds like Hutan is usually a decent display animal (at least better than Indrah); though the isolation of their exhibits from each other will reduce activity. The tigers at Auckland, Hamilton and Wellington are far more active; with the majority of their focus being on the adjacent tigers in their respective exhibits.
Most zoos in the region implement fasting days with their tigers, which reduces anticipation behaviour e.g. pacing, but I’ve never heard of one feeding once a week, which is interesting to hear. I’d imagine he does very little for 2-3 days after eating from the carcass, which is why most zoos feed smaller amounts three or four times a week.
Melbourne feed their tigers only using entire carcasses with one to two weeks between feeds its very incredible to see when you do on the right day
