Both sides make vague accusations that the other is committing animal cruelty, but nothing is shown, or even expressly described. Likely the two worst scenes are the main guy whacking a tiger on the head with his cane when she attacks his shoe and drags him around her enclosure (he then fires his handgun, but not at her directly) and another when someone describes "euthanizing" tigers by shooting them rather than transporting them elsewhere. There are also scenes where they're tranquillized. If you're heavily sensitive to seeing animals in captivity, then avoid it - however there is no outright abuse IMO
