Things to note when raising a hairless cat:
1. Hairless cats only have fine downy fur, which cannot keep them warm. You need to take measures to keep them warm, such as dressing them in warm clothes or turning on the air conditioner to ensure a comfortable indoor temperature.
2. Hairless cats have sensitive stomachs, so you can feed them some pet probiotics regularly to regulate their digestive system and enhance their immunity. 
3. In addition to regular cat food, you should also feed your cat more meat and vegetables to ensure a balanced diet.
4. The midday sun can easily sunburn the skin of hairless cats, so it's best to let them sunbathe in the morning.
5. Feed your cat regularly and in measured amounts to prevent indigestion, diarrhea, and vomiting.
