Instead of having them just bash through any type of wall/fence without consequence to their integrity, have the animals receive injury depending on what type of enclosure structure they're trying to break out of. This way you not only have to worry about rounding up your dinos and patching holes in the fences, but also having to heal them back up or preventing their death. If for example a small herbivore or carnivore is trying to bust open a concrete wall, after a certain amount of hits its health starts to drop and will die if not tranqulized. Or how about a Compy trying to climb out of an electrified fence getting electrocuted to death? Bigger dinos could still realistically bring down the toughest of enclosures but still sustain a certain degree of injury, making bringing their comfort levels back up a bit more challenging.
