Five common problems with domestic kittens:
1. Abandonment issues. If you know you lack patience for pet care and may abandon, rehom, or neglect your pet, it's best not to get a pet lightly.
2. Shedding. It's inevitable for cats to shed, unless they are hairless cats. You should always keep hair removal products on hand at home.
3. Litter box cleaning. Cat poop smells very bad, so you need to clean it every day to keep the environment clean and hygienic for both the cat and yourself.
4. Heat cycle. Female cats in heat will howl all night, while male cats will urinate everywhere. Pet owners can consider spaying or neutering their cats depending on the situation.
5. Illness issues. Pet owners should ensure their cats receive all required vaccinations to prevent illness, as cat veterinary costs can be quite high. 
Things to note when keeping a cat as a pet:
1. Bathe your cat regularly. Cats can get fleas, so you need to bathe your kitten regularly.
2. Avoid excessive contact with cats. Getting too close to kittens can affect your health, as animals generally carry a lot of bacteria.
3. Kittens need to be trained from a young age. Train kittens from a young age to develop good habits, such as urinating and defecating in a designated place.
4. Pay attention to your cat's health. To protect the health of both your pet cat and yourself, your cat should be vaccinated.
