1, different body hair patterns: there are obvious differences in body hair patterns between first-line hamsters and third-line hamsters. First-line hamsters often have an obvious black dorsal line, extending from the head to the tail, with lighter gray stripes on both sides. Three-line hamsters, on the other hand, have three distinct black back lines, the middle back line is relatively wide, and the back lines on both sides are relatively narrow.
2. Different body sizes: There are also differences in body sizes between first-line hamsters and third-line hamsters. The first-line hamster is relatively small, with a body length of about 8- 10 cm. The third-line hamster is relatively large, and its length can reach about 12- 15 cm.
3. Different personality characteristics: First-line hamsters and third-line hamsters are also different in personality. The first-line hamster is active, curious and easy to domesticate, so it is suitable as a pet. The third-line hamster, on the other hand, is relatively introverted and timid, and it takes some time and patience to get close to strange environment and human beings.
