I've found brown bears to find Tygon tubing especially tasty, but I don't
know about acetate tubes. If for some reason the shocker fence doesn't
work for you and you are looking for a lower tech solution, You might try
what seems to work on some food storage systems: handing little sacks of
mothballs around the edge of the thing. This might, I think, avert the
"tasting" behavior, but may not affect play behavior much.
