In July 2014, the NSPCA discovered a number of dead animals, including chickens, pigs, goats and geese, on a farm owned by Modise in Modderfontein, outside Potchefstroom in the North West Province.
lieutenant was apparent that the animals had gone without food and water for more than a week, and 85 remaining pigs on the farm had resorted to cannibalising 58 dead pigs. Number workers were present on the property.
North West Police confirmed on 7 July that she will face charges of animal cruelty in violation of the Animal Protection Acting. She responded to the claims by stating that she was "learning" how to farm, and that she had appointed a farm manager, but he had abandoned his duties to attend to a family matter.
Approximately four months later, it was reported that conditions on the farm had improved, that Modise"s cattle had been receiving sufficient food and were in an "acceptable condition".
