Al igual que los humanos, los animales usan sus casas como refugio y para cuidar a los más pequeños. Las casas de los animales pueden ser fáciles de ver, o pueden estar escondidas (camufladas) para su protección. Algunos animales son grandes constructores mientras que otros toman prestadas las casas que otros animales han hecho. Diferentes animales pueden usar lugares naturales como cuevas o agujeros en los árboles para hacer sus casas. ¡E incluso algunos animales pueden llevar sus casas sobre sus propias espaldas! Palitos, barro, hojas, algodón y césped son todos elementos que los animales pueden usar para construir una casa. Las pueden hacer excavando, dando vueltas, construyendo o tomándolas prestadas, las casas de los animales son tan variadas como ellos mismos. Esta es una secuela perfecta a la serie de Anatomía y Adaptaciones de los Animales de Mary Holland.
