I'd go for naturediet or just tins of sardines as that's easy to feed. We are taking our two on a boating holiday for a week in June with no freezer so they'll be getting naturediet and sardines (maybe I can get them little fishing rods and they can catch sticklebacks for their dinner?
I can just see that, Zorro would be soooooo bored and then the excitement of something pulling on the line would be too much, he'd end up capsizing the boat with all his jumping up and down
- erm, time for me to go home I think, getting a bit carried away
).
