A 10-day-old kitten without a mother requires especially careful care. Kittens have poor thermoregulation and need a warm environment. You can use an electric blanket or hot water bottle to help maintain their body temperature, but be sure to keep the temperature moderate to avoid burns. Also, ensure the kitten's bed is soft and comfortable and placed in a sheltered location.

Ten-day-old kittens need special kitten formula, which can be purchased from designated pet stores according to the veterinarian's advice. Prepare the formula with warm water and feed the kitten using a syringe or a special bottle. When feeding, pay attention to regular times and quantities, generally every 2 to 3 hours, feeding until the kitten's belly is slightly swollen.
