There is no definite answer to this question, because every cat's situation is different. Generally speaking, cats' fur can provide some warmth and make them adapt to certain cold weather. However, some cats may be more sensitive to cold, such as older, smaller or in poor health.
If you observe your cat showing signs of discomfort in cold weather, such as trembling, looking for a warm place or unwilling to go out, it may be a good idea to put on suitable clothes for it. Clothes can provide extra warmth and help cats stay comfortable.
However, there are some things to pay attention to when wearing clothes. First of all, make sure the clothes are the right size and will not restrict the cat's activities. Secondly, choose a material suitable for cats, which is soft, comfortable and easy to clean. Finally, observe the cat's reaction. If they don't like wearing clothes or feel uncomfortable, don't force them to wear them.
In short, deciding whether to dress a cat depends on the cat's personal situation and needs. If you have any questions, you'd better consult a veterinarian.
