1. The normal respiratory rate of rabbits is 20-40 times per minute, and the respiratory rate of juvenile rabbits is 40-60 times per minute.

2. The heart size of rabbits is related to their body size, and the heart rate is related to the size of the heart, so usually the heart rate of small rabbits will be faster than that of large rabbits.

3. When rabbits are frightened or perform strenuous exercise, their heart rates will increase much faster.

Tip:

Rabbits are homeothermic mammals. Their metabolism generates a lot of heat, but they do not have sweat glands and cannot regulate their body temperature through sweat glands, so they can only dissipate heat through breathing and excretion. In addition, the normal body temperature of rabbits is between 38.5-39.5 degrees. If it exceeds this range, it means that the rabbit may be sick.
