Roof to roof, Federico the cat visits all his families everyday: Tadeo and his grandparents, Anna and her two Moms; Virginia, with her Mom and Dad, Paula and her two Dads... All of them different, all of them loved by Federico. Unconditionally. This little jewel is perfect to show the smallest of the house that love can be found in any family. By author and compromised activist for diversity Mili Hernández and illustrator Gómez. El gato Federico visita de tejado en tejado a todas sus familias. A Tadeo, que vive con sus abuelos; a Ana y sus dos mamás; A Virginia, su papá y su mamá... Son familias diferentes y Federico las quiere a todas por igual.
