Things to note when keeping a Ragdoll cat at home:
1. Ragdoll cats have relatively delicate digestive systems. Do not change their food easily to avoid symptoms such as vomiting and diarrhea.
2. Owners should clean their cat's ears regularly to prevent earwax from accumulating and harming the cat's health. 
3. Keep fragile and dangerous items out of your cat's reach to prevent injury.
4. Ragdoll cats shed a lot, so owners need to brush their cats' fur every day and clean up the shed fur promptly.
5. In addition to cat food, you should also feed your cat more cooked egg yolks, chicken breast, and other nutritious foods to ensure a balanced diet.
