Can cat fur be shaved?
Cat fur can be shaved, but it is not recommended.
Shedding is a very normal phenomenon for cats. To avoid the hassle of cleaning after shedding, many people want to shave their cats completely. However, it's not recommended to shave a cat's fur completely, as this can easily lead to skin diseases. Cats' skin is quite sensitive to external factors. If you shave their fur, bacteria and fungi in the air can directly come into contact with their skin, making them more susceptible to various skin diseases.
If cats are exposed to direct sunlight, their skin can easily be burned by ultraviolet rays, preventing their fur from growing back. Cold weather also makes cats more susceptible to catching a cold, so it's advisable not to shave your cat unnecessarily.
If the reason for shaving a cat's fur is to more quickly identify the cause of its illness and thus allow for rapid treatment, and if the cat is having difficulty breathing, it's likely due to hot weather. In these cases, careful observation is necessary. If either of these symptoms appears, you can trim the cat's fur appropriately, or even shave it completely, to make the cat more comfortable. 
Dangers of shaving a cat
1. Causes skin damage in cats
After a cat's fur is shaved, it loses its protective barrier, allowing sunlight to directly penetrate its skin, making it very susceptible to sunburn. Furthermore, the exposed skin makes it more vulnerable to scratches and cuts.
2. Increased risk of developing skin diseases
Shaving a cat's fur leaves its skin unprotected, greatly increasing the risk of skin diseases such as parasites, fungi, and bacteria! For the sake of your cat's health, it is not recommended to shave your cat's fur unless permitted by a veterinarian.
3. The cat exhibits a stress response.
We all know that cats are prone to stress reactions when stimulated. Once a cat experiences a stress reaction, it may suffer from loss of appetite, urinary retention, and infectious peritonitis, with the most serious consequence being sudden death. Never underestimate the harm that shaving can cause to cats. Don't take stress reactions lightly, and certainly don't treat your cat's life lightly.
