I enjoyed this film very much. Jay North does a fine job as a child who has raised a mountain lion from birth but because he has to move with this family to the city, the mountain lion has to be put in a zoo that is poorly funded and with tiny cages. As a result, Jay North's character frees all the animals there 45 minutes into the film. The middle part then is more comedic as the animals enjoy their time away from the cages. Longtime character actor Andy Levine and Martin Milner are wonderful in their roles as the zoo caretaker and zoo director, respectively. Now zoos are more animal-friendly but when this film was made, many zoos were like jails with cramped cages and the rights of animals was an afterthought in zoos. This film enlightens the public in that regard and does so in an entertaining and heartfelt way.
