The hamster's nose makes a popping sound and rubs its nose, which may cause respiratory diseases.

1. Catch a cold.

First of all, the owner should observe whether there are any symptoms accompanied by a runny nose, and also observe the hamster's mental state, whether it is eating and drinking normally, and whether it has appetite, etc. If the hamster's mental state and appetite are a little poor, it may be that the hamster has an upper respiratory tract infection, resulting in a runny nose, popping sounds, and nose rubbing movements. This situation is mostly caused by cold weather or failure to keep warm. If the symptoms are mild, you can put it in a warmer place and put some isatis root in its water bottle. If the symptoms are severe, it is recommended to send the animal to an animal hospital. Nowadays, there are specialized pet doctors who can provide treatment under the guidance of professional doctors.

2. Allergic reaction.

It may be that the hamster has nasal allergies, causing symptoms similar to sneezing. In this case, the owner needs to make his own judgment and observe whether it is caused by bedding allergy, the surrounding environment, toys, or pungent smells, etc. If a hamster is allergic, the hamster can recover as long as the allergic factors are eliminated.
