Kitten’s teeth are too sharp and cannot be trimmed. Trimming a kitten's teeth is likely to damage the gums, tooth roots, etc., and may cause the kitten to suffer from oral diseases. Usually kittens will start to lose their teeth when they are 4 months old, and all the teeth will be replaced by permanent teeth. If the teeth are too sharp, the owner can prepare a pet-specific molar stick for the kitten to help the kitten wear the sharp teeth. When raising kittens on a daily basis, you can prepare dry cat food for the kittens, which can also be used to grind their teeth.
