Oliver the cat really couldn't believe her eyes when a bath bomb fizzled in front of her very eyes – so much so, she stood on her hind legs and couldn't stop staring.

This video, taken in Macon, Georgia, shows the cat's reaction.

The filmer said she had had a long day and decided to relax in the bathtub with a bath bomb from Lush. She took a video to send to a friend who asked how the bath bombs were.

"I didn’t even know my cat Oliver had snuck into the bathroom, but out of the corner of my eye I saw orange movement and looked to see her standing on her hind legs looking VERY concerned," she said. "She’s never done that before!"
