One-month-old cats should not have all their teeth and need to eat liquid food, but don't feed them in bags, they will have diarrhea. You can buy milk powder, rinse it with boiling water, and then cool it, preferably cat milk powder. And cats don't need calcium supplements, so don't feed calcium-containing milk powder. You can buy some rice noodles and feed them with milk powder. Cats need carbohydrates, and both rice flour and rice contain carbohydrates. When the cat's teeth are full, almost two months later, you can feed the cat food. You can go to the pet store to buy food for the kitten. In the early stage, it should be made into paste with boiling water for cats to eat. In about three months, it can chew dry cat food, and then you can feed it all the time.

Kittens are afraid of cold, so the cat nest prepared for them can be thicker and placed in a warmer place at home. Put the litter box near the cat's nest so that it can go to the toilet. Without much teaching, it will go to the toilet in the litter box by itself.

I hope your cat can grow up healthily and happily under the careful care of its owner!
