NPR's Ailsa Chang talks with directors Trevor Beck Frost and Melissa about "Wildcat," their documentary about a couple working to rehabilitate orphaned ocelots in the Amazon rainforest.

Wildcat Rated R for suicidal ideation, physical self-harm, animal-on-animal violence and animal death. Running time: 1 hour 46 minutes. In theaters and on Amazon Prime Video. Wildcat.

The nature documentary "Wildcat" transcends the genre to go deep into the bond between a month-old ocelot kitten and a British army veteran with PTSD.
