Often, cats can be really territorial during cat sitting. I once had a cat that hissed at its own reflection in the mirror. It was like it was having a stand - off with an intruder. It would paw at the mirror and meow loudly, thinking there was another cat in the room. It was hilarious to watch.
A common and funny scenario in cat sitting is when cats play with things they're not supposed to. I remember a cat that got hold of a roll of toilet paper and unrolled the whole thing across the living room. It was running around in the paper like it was in a snowstorm, and by the time I stopped it, the room was a mess. But it was really cute.
There was this one time when I was cat sitting a very lazy cat. It would find the sunniest spot in the house and just plop down there all day. One day, it found a box near the window and squeezed itself into it. Then it fell asleep with its head hanging out. It was so cute that I took a picture and sent it to the owner.
In a story, the rat might pretend to be dead when the cat approaches. The cat would be all proud thinking it has won, but then the rat jumps up and runs away. Another funny thing could be that the rat builds a little fort out of boxes and dares the cat to come in. The cat tries to get in but gets stuck in the small entrance, looking all silly.
Well, sometimes a funny Christmas card can make someone's day. For example, if a person is feeling down during the holidays, receiving a card with a comical picture or a witty message can instantly lift their spirits. It might be a card that has a misprinted holiday pun that turns out to be even funnier than the original intention.
The cat would likely jump off quickly because it would feel the heat and it's uncomfortable for the cat.
The story where a cat gets tangled in a ball of yarn is really interesting. It ends up looking like a furry, moving yarn monster. Another interesting one is when a cat tries to steal food from a dog's bowl while the dog is sleeping. The cat tiptoes over, but the dog wakes up at the last second and the cat has to make a hasty retreat.
There's a cat that used to perch on top of the TV. One day, during a really exciting football game, it jumped right in front of the screen as if it wanted to join in. And then there was a cat that managed to open the refrigerator door by itself and helped itself to some leftover chicken. It was quite a sight to see the cat sitting in the fridge with a piece of chicken in its mouth.
One common funny thing is getting the pedals mixed up. People often step on the wrong pedal in the heat of the moment. Another is misinterpreting the examiner's instructions.
One funny thing is when customers misread product labels. For example, in a pet store, someone thought a dog shampoo was for humans because of the fancy packaging. They asked the cashier if it would make their hair shiny like a dog's coat. Another is when salespeople accidentally mix up their sales pitches. A guy selling electronics started talking about the features of a blender when showing a customer a laptop. It was really confusing but also hilarious.
At a sleepover, a girl found a louse on her pillow. She decided to draw a little face on it with a marker. Then she and her friends made up a story about the 'friendly louse' that was lost and looking for its family. It was a very creative and funny way to handle the situation instead of being disgusted.
A thong can get stuck in a zipper which is quite a funny and awkward situation. You end up hopping around trying to get it free.
