Kittens will have teeth when they are about 2 weeks old, and they will all have teeth when they are about 6 weeks old. When the kitten is 4-6 months old, the kitten will go through the tooth replacement stage and replace all the deciduous teeth with permanent teeth. At this time, the cat's desire to bite will be stronger. You can prepare some molar sticks or relatively hard toys to help the deciduous teeth fall out. ​​​​​​

At this time, cats may bite cardboard boxes and other items at home to pieces, and they may also like to scratch furniture and other items. The owner must train the cat well at this time, and it is only allowed to sharpen its claws on the scratching board and teeth on the teething stick.
