Eva Gabor and Pat Buttram were both starring together in the TV series Green Acres (1965) while recording voices for this animated film.

The last film in which Eric Larson worked as a supervising animator. From then on he concentrated on training the younger animators that came to the studio during the seventies and eighties.

The character of Scat Cat was designed to be voiced by Louis Armstrong. The character's look was modeled after Armstrong - the way he played his trumpet, his roly-poly physique, right down to the prominent gap between his teeth. However, Armstrong was unable to record a single line due to illness. His replacement, Scatman Crothers, was directed to "Pretend you're Satchmo."

As the crate with Edgar in it slides through the barn door, the padlock suddenly appears on its latch.

In the beginning credits, they show that the song She Never Felt Alone by Robert B. Sherman and Richard M. Sherman is in the movie - but the song never played in the film. The first part was supposed to be played before the lawyer came into the bedroom that the will was created at by the old woman, and the second part was supposed to play when Dutches explaining to Thomas why she has to return to Paris.

In the "Scales and Arpeggios" scene, Toulouse jumps on the piano with orange and green paint. At the end of the scene, he has orange and blue paint on his paws.

Toulouse the Orange Kitten: I told you it was Edgar.

Thomas O'Malley: Humans don't really worry too much about their pets.

Duchess: Oh, darling. That's only a little frog, my love.
