The word “tense” comes to mind when I watched this video. Once again this is a Chinese hosted video and I do not recall having seen a video of a veterinarian working in his clinic like this one. It’s a little bit challenging to watch but if you can it’s interesting.
I suppose the moral behind the video is that you should not let your cat feed on a piece of discarded fish that you may have eaten yourself. I don’t know whether this is typical in China; to throw bits of waste human food like this at a cat. Perhaps that didn’t happen. I have no idea. The cat does not look like a stray so I’ll presume that she is a domestic cat.
