1. In winter, cats' paws get cold, so they like to tuck their paws in to keep them warm. Owners should take timely measures to keep them warm.
2. When cats relax and are in a relaxed state, they also like to tuck their paws in, just like people sit cross-legged. 
3. If the owner wants to trim the cat's nails, the cat will feel scared and resistant, and will try to hide its paws.
4. When a cat doesn't want to interact with its owner or be disturbed by anyone, it will put its paws inside its mouth.
5. When a cat is sick or injured, it will also tuck its paws in. Owners should check the cat's paws for injuries or illnesses in a timely manner. If anything is found to be wrong, seek veterinary care immediately.
