There is no need to shave blue cats in summer. Blue cats have no pores or sweat glands on their bodies. Shaving will not help them cool down. Instead, it will damage the hair follicles of the body. When shaved blue cats stay in the sun It will be burned by ultraviolet rays and increase the chance of skin diseases, so do not shave blue cats in summer. The owner can place the blue cat in a ventilated and cool room, or turn on the air conditioner for the blue cat to help cool it down.
