A cat experiences sights, sounds, and smells just way a human newborn does. Every new animal, person, and thing it experiences shapes its personality. All of these interactions and exposures during the ensuing weeks have a substantial impact on a kitten’s ability to socialize.

A kitten will start to become more autonomous and inquisitive after leaving its mother at roughly two to three months old. These cats may be receiving medications, or they may be eating particular foods and supplements, to support various physiological systems. A kitten grows swiftly throughout these months; by the time it is six months old, it is roughly the same size as a 10-year-old child.

A series of vaccinations are required for kittens, and they are often spayed or neutered at around six months of age. Your veterinarian is likely to discover any genetic or congenital issues at this time.

Cats typically survive until their late teens, therefore they are not yet regarded as senior citizens, despite the fact that some veterinarians may start referring to your cat as a senior once it is approximately seven or eight years old.

Cats live a very long time. If cats were people, they would be about 100 years old by the time they are 20, making a 15-year-old cat almost the same age as a mid-70s human. Geriatric cats should visit the vet at least once every six months if they will be 15 years or older. It will explore its surroundings when its adult teeth begin to erupt, get into mischief, and possibly chew on things it shouldn’t. Cats usually spend the majority of the day napping, which results in age-related impairments in their hearing and vision.
