The socialisation period in puppies and kittens is a critical developmental window. Inadequate socialisation creates lifelong welfare deficits through fear, anxiety, and behavioural problems.
The socialisation period represents the highest leverage point for companion animal welfare across the entire lifespan. Animals that experience diverse positive encounters with people, animals, environments, and handling during this sensitive period are dramatically less likely to develop the fear and anxiety disorders that cause lifelong suffering. The puppy and kitten farm industry systematically fails animals during this period through isolation, kennelling, and early separation. Responsible breeders who maintain animals in home environments with appropriate stimulation from birth produce animals with measurably better lifetime welfare outcomes.
