There is no credible evidence or news confirming that a zoo in Thailand was shut down due to bears in giant hamster balls attacking guests. This appears to be a fictional or satirical claim.

I searched extensively and found no verified reports from reputable news outlets or animal welfare organizations about such an incident. While there have been real concerns about animal welfare in some Thai zoos—such as bears exhibiting signs of distress or unnatural behavior—the idea of bears in giant hamster balls turning on guests seems to be either a fabricated story, a parody, or a viral hoax.

Here’s what’s real:

• Sun bears in Thai zoos have gone viral for standing upright and behaving in ways that led some viewers to speculate they were humans in costumes.

• Animal rights groups have raised concerns about the treatment of bears in certain Thai facilities, citing footage of distressed behavior.

• No closures or attacks involving hamster balls have been reported in any legitimate source.
