When a newborn kitten opens its mouth to breathe, it may be because the nasal cavity is blocked, causing difficulty in breathing. The owner should pay attention to check whether there is mucus or other foreign matter blocking the kitten's nose. You can use a baby cotton swab to help clean it. It is also very likely that the amniotic fluid in the kitten's nasal cavity was not drained as much as possible when the kitten was just born, resulting in amniotic fluid remaining in the cat's upper respiratory tract, causing the kitten's upper respiratory tract infection. It is recommended to send the pet for treatment.

How to feed a cat that is just a few days old:

1. It is best for newborn kittens to drink breast milk. If there is no breast milk, it is recommended to feed them with goat milk powder. Never feed kittens milk, as many cat flavors are lactose intolerant and can cause diarrhea.

2. Newborn cats are very afraid of cold, so owners should keep warm. It is best to place a heating lamp in the kitten's nest and wrap the kitten tightly in a blanket.

3. Newborn kittens have weak resistance. Pay attention to the hygiene of the kitten’s living environment. The blankets in the nest should be changed every day. When preparing to handle kittens, it is recommended that you wash your hands with soap and water.
