Thank you Louis, Shweta and Andrew!
Perhaps this needs some more info...
First, I'm not irritated with the cat, really. The cat is doing what it's doing, and finding out the correlation with my mind took away all irritation that was there before toward the cat. Now, the irritation is solely towards me. I'm the one not getting it! I have very high demands on myself - I should be able to solve this by now - a conviction that is obviously not true since I'm not solving it.
Because the anger is towards myself it's hard to do the Work. It's not recommended to do on oneself, hard not to dive into more self-judgement if you start go down that road!
(Louis, I have a comment on the link about the secret, but I'll post it in that thread instead.)
Shweta, thank you for the angle "I'm just being practical", that felt nice. And I agree, it definitely needs to be inquired... but how?
Andrew, you are right there... It IS my own fault, that's the guilt and self-judgement there! I sometimes close the door as well, but since I live in a small flat I'd like to give my 2 cats as much space as possible to move around in. And... what's worse - my cat can actually pee anywhere. Mats, kitchen table, bathroom floor instead of in the litter box. So I clean up here and there. It's the bed that's worst to clean, though...
I heard about someone having this bad problem, and they found out eventually that the cat was old and senile. My cat is 16, so that might be the case... But I don't really think so, since the correlation is so obvious with my thoughts.
What has been working best is if I send my cats lots of love energetically during the days, and with the thought/intention:
"I give up - I can not control where you pee. I just trust you will pee where you have to. Universe makes no mistakes." Then she doesn't pee!!!
Then I forget to send love and to surrender. I think it's "over and done" and forget about it since the problem is not there anymore.
Then she suddenly pees again.
I feel I'm sort of on the right way, but the coin has not dropped yet...
