My brother went on vacation and left his hamster with me. It hasn’t given me any trouble so far but I noticed a ball sized lump forming on his neck. I’m worried what should I do?
Hamsters are very curious animals in terms of their behavior and physiology. They also have many instinctive behaviors that they continue to develop despite living in a comfortable environment. One of them, for example, is the tendency they have to pile on their cheeks to store and transport food from one place to another. This behavior comes from his free life. They do this because they need to be fed during the coldest winter months and therefore carry it to their burrows. Regarding your comment, it is possible that the package in question has its origin in a previous tradition. The problem is that sometimes this buildup leads to infection and abscesses. This may be the reason, but it cannot be ruled out that it is a tumor. Therefore, it is best to go to your vet as soon as possible so that he can directly see what is happening.
