Kittens should not eat oranges because oranges have a pungent smell that kittens dislike. In addition, a series of acidic fruits such as tangerines, oranges, and grapefruits are not suitable for kittens. Long-term consumption of these fruits can lead to cell necrosis, vomiting, and even death in kittens. 
Dietary precautions for kittens:
1. Feed small, frequent meals: Kittens are growing rapidly and need a lot of nutrition, so they need to be fed 4-5 times a day. However, the portion size should not be too large, otherwise they will not be able to digest it all. It is recommended that owners feed their kittens at regular times and in measured amounts, allowing them to eat small, frequent meals, which is better for their digestive system.
2. Avoid feeding treats: Try not to feed kittens treats. Cat treats are generally less nutritious than their main meals, and feeding them too many can lead to picky eating. Human treats should also be avoided, as the high oil and salt content can easily cause gastrointestinal upset in cats.
3. Encourage water intake: When kittens are young, owners should encourage them to drink more water to develop a good drinking habit. If they really don't like to drink water, you can add a little water to their food and stir it in before feeding them. This will also help them stay hydrated and prevent urinary problems such as urinary stones.
4. Keep probiotics and anti-nausea medication on hand: Kittens' digestive systems are much more delicate than adult cats', so owners can give them probiotics to help with digestion. If your cat still has digestive issues and vomits frequently after reaching adulthood, it's recommended to give it some anti-nausea medication like Propionate to relieve vomiting, diarrhea, and other gastrointestinal problems.
