He waited for their cat to go to the bathroom to do its business
When OP saw the cat pooping on the litter, he meowed at him until he finished and left
OP thought this was the best way to make the cat see how annoying it is to have someone meow at you while you're in the bathroom
He and his GF had an argument about it. She said he is giving their cat "litter box anxiety," which OP thinks is a made-up thing and he doesn't think he did anything wrong.
The Redditors supported the GF's claims and said OP is going to give their cat an issue if he keeps meowing at it
The cat will look for another place to poop where no one will bother him and it could be on OP's bed
I hope the cat knows which footwear are OP's
The cat probably didn't even know why he was being yelled at in the first place, animals are not humans — they have no concept of revenge or whatever OP was trying to do
Or it could be looking out for OP's safety. Animals feel most vulnerable when they are pooping or peeing, they think humans are the same way and are trying to protect us
OP should do more research before dismissing his GF's claims of litter box anxiety
If it bothers him so much, OP can wear noise-cancelling headphones because meowing at his cat is not the solution he thinks it is
Their cat isn't going to know that OP scaring him was a punishment for him doing the same thing while OP was in the bathroom the day before
If OP keeps at it, we will be hearing all about it soon enough
It's all fun and games until you find yourself waking up to cat poop all over the house. Did OP learn his lesson faster than his cat developed litter box anxiety?
We'll have to find out, or at least OP will unless he changes his vengeful thinking. If he doesn't, it will affect not only his cat but his GF as well since he dismissed her opinion so quickly.
