What’s the dumbest thing your pet has ever done that made you question their entire species?

My cat would parade in front of feral dogs like it was nothing. Zero survival skills.

My hamster ran directly into a wall. Then did it again like it was gonna work the second time. I kinda just sat there questioning everything.

My dog eat his shyyt like wtf?

We have 1/4" high transition strips that "transition" our living room wood floor from the hallway tile on 2 sides. Our dog (dachshund) approaches, mentally prepares, false-starts and finally jumps over these like she's qualifying for the Olympic high jump. And yet, she will go up and down stairs with no drama whatsoever.

My cat plays with her tail and gets serious with it

Non-recognition aggression in cats. Every time without fail when we take one of our cats to the vet and bring him back, the other one is like, "Could this cat that looks looks just like my brother with whom I have spent every second of every day for 15 years be back? Nooo, he smells a little different, so he must be an entirely different cat and an intruder on my territory, I will try to murder him for the next 24-48 hours. Makes perfect sense." Say what you want about dogs, they never do this dumb shit. I'd laugh more about it if it wasn't so dangerous. I've actually heard of cases where the non recognition turned into a cycle of aggression and the two cats never recovered. In one case it didn't stop for months and months and one of the cats needed to be rehomed.

Never had a pet. My friend's golden though didn't know how to slow down and stop when she ran. When we tried playing fetch with her, she would run full speed until she reached the object, overshoot it and then tumble on the ground.

My cat will sometimes jump in the bathtub and chase her tail. 😆
