When choosing a kitten, it should never be less than 8 weeks old. In fact, when getting pedigree kittens from reputable breeders, you will likely never get a kitten that is under 12 weeks old. The advantages for getting a kitten is that they are very playful, alert, tiny, and can be more easily trained. However, the disadvantages are that they’re much more fragile, energetic, and destructive.
Many people avoid choosing adult cats because they are seen as being less cute than kittens. However, choosing older cats come with a wide range of advantages. For example, older cats are more independent, typically less destructive, may already be spayed/neutered and have its vaccinations, more laid back, and more affectionate.
