我发现猫老是啃纸箱子，可能是因为缺少微量元素而患了异食癖，也可能仅仅是在玩。异食癖其实是一种正常饮食结构失衡的反馈，如果猫有异食癖，它们可能会选择咀嚼纸箱，并期待品尝纸箱的味道。假如你观察到猫咪在啃咬纸箱后有吞咽行为，请考虑异食癖的可能。

许多猫咪出现啃咬纸箱的举动通常是出于喜爱，它们把纸箱作为了好玩的玩具，享受啃咬纸箱的过程。有些猫可能喜欢用牙齿磨擦paper box 的感觉，而另一些猫则可能喜爱bleaching paper boxes时传出的声响，也有些cat will通过bleaching paper boxes 的举动来引起cat lover 的关注。

如果你的 cat 因无聊而啃paper box，你可以购买 cat climbing structures、mice toys、dolls、teasers等物品玩具以便你的 cat play.

还有一些情况，是由于cat 在换牙期，因为 teeth aching 而要blow off steam by chewing on things like paper boxes. In this case, you can buy chew toys to help your cat gnaw and relieve the discomfort.

So, it's not just about the lack of nutrients or boredom; there are various reasons why cats might enjoy chewing on cardboard. And as their human caregivers, we should be aware of these possible causes and provide our feline friends with suitable alternatives to keep them occupied and happy!
