When feeding a one-month-old kitten, the first step is to gradually transition it to solid food. Initially, you can soak the kitten food in goat milk powder to soften it and aid digestion. As the kitten grows, you can gradually reduce the proportion of milk powder until it is completely transitioned to dry kitten food.

In terms of hygiene, you need to provide your cat with a clean litter box and clean the litter regularly to maintain a clean and hygienic environment. The type of cat litter should be suitable for your cat's age and size, making it easy for them to use.
