家 combines 宀 (roof) and 豕 (pig), reflecting an ancient view of a household as a place where pigs were kept under the roof, symbolizing settled domestic life.
Under a roof 宀, a pig 豕 is kept. In ancient times, raising pigs at home meant a settled family life, so 家 means house, home, or family.
For カ, imagine a car parked in front of the house: car -> カ, and the family's home is where the car is.
