An amusing video has emerged of a cat discovered using a human toilet.

In the footage, captured secretly in a home in Marina, CA, USA, the cat investigates the bathroom fixture before balancing on the seat and doing her business.

“I'd noticed that someone had not been flushing the toilet in one of our bathrooms,” the filmer later wrote online.

“All of the family members claimed to be flushing. I'd also noticed that the cat box was suspiciously clean (with the exception of faeces). I suspected that she might be using the toilet, so I set up a video camera and let it run overnight. The video footage revealed that she was the culprit who was going in the toilet but not flushing. She apparently started doing this on her own.”
