This is my first time of reading something like this. I haven't seen any video that cats react to cucumber. I will check YouTube to know if it's truth. I don't have a cat right now, assuming I have one, I will try it out with her.
I've heard about it but never cared about going to find the video to watch. I'm guessing it's not a big thing now otherwise, I'm very sure so many videos of it will be dumped on Tiktok by different users.
I checked it out and frankly speaking, I didn't know why they react like that to cucumbers. I think nobody understands the reason too because the comments wasn't giving a good explanation.
Cats are not afraid of cucumbers. They might be startled when they see a cucumber by sudden but that doesn't mean they are afraid of it. This is just a nonsense going viral online.
