Many friends will keep some macaroni rats, but they don't know much about their conservation knowledge, such as what are the disadvantages of keeping macaroni rats? Disadvantages are: 1, poor personality, and timid in biting. Before it is fully cooked, macaroni rats may bite, and they will bite wildly when they catch it from the back of their necks. Also, don't poke it suddenly while it is sleeping. Macaroni rats will bite just like that, and they especially don't like being woken up. 2, the ability to recognize the owner is poor. It is difficult for macaroni mice to recognize the owner, and it will take a long time to get familiar with the owner. 3. The macaroni mouse has a low IQ, is sluggish, inflexible and has no curiosity, so it is not fun to raise.
