Ensuring that clients understand the importance of socialization—and how to do it right—is the key to raising a calm pet that is comfortable in multiple surroundings.

It is not uncommon for cats to run and hide when visitors enter the home or when they are exposed to a carrier for travel to the veterinary clinic. Thirty-eight percent of cat owners find it stressful to take their cat to the veterinarian, and 58% report that their cat hates going to the veterinary clinic.1 Cat owners often consider fear-related reactions associated with visitors, veterinary visits, husbandry care, and vehicular travel to be “normal” behaviors, but they don’t have to be.

Keeping cats calm and comfortable begins with early exposure and positive socialization. With proper socialization, cats are more amenable to receiving veterinary and home health care because they are more tolerant of handling.

What Is Socialization?

Socialization is the process of learning to communicate with and relate to humans, members of the same species, and other animals. A hallmark of this period is social play.

For cats, the socialization period occurs between 2 and 7 weeks of age but can extend up to 14 weeks. It begins with self-play and batting objects followed by social play among littermates by about 3 weeks.2 Social play increases from 4 to 11 weeks of age and peaks by 12 weeks. It begins to wane after 12 weeks, and object play predominates until about 4 months of age when it begins to decline gradually.2

Socialization includes localization, which is the process of learning to be attached to specific environments. Cats tend to be most comfortable with environments to which they were exposed at a young age. Both socialization and localization shape future behavioral responses and prepare cats for myriad social and environmental experiences later in life.

Socialization and localization should include pleasant exposure to various environments, sounds, people, animals, and novelty. Pleasure can be enhanced by using “kitten-approved” reinforcers, such as special treats, toys, and petting around the head.

Early studies evaluating the effect of kitten handling on subsequent behavior toward people3-5 showed that handling by multiple people for as few as 5 minutes a day can have lifelong benefits, especially if done prior to 7 weeks of age.3-5 Other studies have suggested that friendliness and boldness of temperament may have strong roots in genetics, specifically linked to the behavior of the tom.6 Kittens sired by a sociable tom are more likely to be sociable. Kitten socialization with people can be facilitated by the presence of the queen if she is sociable and calm. Kittens are observational learners and will take social cues from the queen. It is much more difficult to socialize a kitten to people and other animals without early positive experiences before 7 weeks of age. By 14 weeks, social play between kittens is more likely to result in fighting.

A cat that is obtained after the socialization period, with an unknown or suspected lack of early positive experiences, can be socialized, but the process is much more difficult and ultimately will take longer.

Client Education Is Crucial

It is important for clients to understand that socialization is not simply about exposure to varied situations and people. Rather, it is about making exposure fun and positive from the start.

The following recommendations can help clients make the socialization process more effective:

  • Take the kitten to socialization classes, often called "kitten kindergarten." These group classes offer controlled exposure to new people, cats, and environmental stimuli (Figure 1).
  • Ensure gentle daily handling by multiple people. Gentle massage while providing special treats will make the experience pleasant. Social experiences with people may include kitten parties or inviting friends to the home to play with the kitten. Catnip may be sprinkled on the floor to foster exploration. Synthetic feline pheromones may enhance socialization experiences and reduce fear in some individuals. Wand toys may be offered to engage the kitten in interactive play with visitors yet at a social distance from unfamiliar people. Visitors should avoid potentially threatening body language such as direct approach, direct eye contact, and excessive petting. The kitten should be allowed to make the first move. “Playing hard to get” and ignoring the kitten initially may spur its curiosity.
  • Introduce kittens to travel carriers at an early age. The carrier should be left out in the environment for exploration, with comfortable bedding, special treats, and toys be placed inside to entice entry. Special meals fed in the crate make for continued pleasant experiences into adulthood.
  • Expose kittens to vehicular travel at an early age, once acclimated to the carrier. Be sure the kitten has good footing to add a sense of security. The carrier and the bedding inside should not slide. Generally, the safest place for the carrier is behind the front passenger seat. Short trips around the neighborhood may be paired with special meals fed in the carrier. Likewise, regular fun visits to the veterinary clinic, including delectable treats from veterinary staff members and exploration of examination rooms without the need for physical or medical care, can allow for pleasant associations.


Proper socialization of kittens involves planning and preparation. Group kitten socialization classes and kitten parties can make cats more adaptable to handling and being transported to new environments. Remember that socialization and exposure are only valuable if they are enjoyable for the kitten.

Advising your clients to take a positive proactive approach from the start will prevent the need for “rehabilitation” later, and foster a better relationship.
