But then father Siraj Waggie, 36, posted on Facebook, reassuring everyone that the goat was part of a petting zoo hired to celebrate his seven-year-old son's birthday.
"It was his idea to do the petting zoo. He loves animals. We are always at petting farms. Whenever it is a holiday we go to a farm with him," said Waggie, adding that the concerned animal lovers should have asked him what was going on.
Waggie, who has been living in the area for three years, said he chose not to react aggressively, instead deciding to put the ''hilarious'' incident behind him.
A "deeply sorry" Furniss later posted an apology, the Mail & Guardian reported.
"I am beyond devastated that I have hurt people and caused pain and outrage. Please accept my humble apology,'' she wrote.
