The decision of whether or not your cat needs to wear a sweater will depend on the area where she lives. If she is from a cold place, letting her wear a sweater may be beneficial for her, but if she does not, she may not need to wear any type of clothing.
Also, you must consider the type of fur that your cat has. If your cat has long, thick fur, it may not be advisable for her to wear a sweater or any type of clothing. But if she has short hair, then letting her wear a sweater may help her in maintaining a warm body temperature.
Consider the size of the sweater and the materials used to make it. It must not be too loose or too fit to prevent your cat from feeling uncomfortable. The materials used should be pet-friendly too to prevent causing any skin irritation.
