Generally, first-line hamsters are the most vicious. The blush on the first line is sharper, and the ears are much larger than those on the third line. First-tier hamsters tend to be more grumpy than third-tier hamsters. The individual differences are not very obvious.
Most first-line hamsters are very good-looking, but they have fierce personalities, and it is not easy to develop feelings with them. Regardless of their ferociousness, they can all be ranked as the most ferocious hamsters. Therefore, when a first-line hamster first arrives in a new home, the owner should not touch it to prevent being bitten.
