Cats don’t lose their teeth like humans do because their teeth are very hard and have remained so for a long time. Cats’ teeth are used to bite and gnaw on animal fur and meat, so their teeth need to be very hard. In addition, cats’ teeth are rarely corroded by food and drinks, which is one of the reasons why their teeth are less likely to fall out.
However, cats' teeth are not completely immune to falling out. As cats age or become ill, their teeth may become brittle and may fall out. Some cats lose teeth due to periodontal disease or other diseases. Therefore, in order to keep cats healthy, their teeth should be cleaned and checked regularly.
