<human>: Hi there,
 
as the title says my cat has peed on my bed twice in the span of a month and a half maybe two. I have tried going online but have found little help. 
Naturally, I thought about posting my issue on reddit and seeking the wise council of its users in the hopes of finding a solution to this particular predicament. 

WARNING WALL OF TEXT BELLOW: 

Here are the details of my case: My cat is roughly two years old, and I have had her since she was kitten. She is an orange tabby and her name is Eevee (like the Pokemon). About two months ago (end July-beginning of August) as I noticed she started scratching my mattress as if she was digging, then one night as I notice she had urinated all over my bed. Having been the first time I decided to dismiss as a fluke, she had just seen the vet for her yearly checkup and all was fine. 
Tonight she did it again ! 
I know its not a medical issue because I have called the vet and they informed me that since she was behaving normally (eating, drinking, playing) that it was probably a psychological problem. 
Now here lies my problem: I have not changed her food in over 3 months, I have been using the same litter for a year, I scoop out her litter box every 2-3 days while doing a full clean of the box every 1-2 months. 
I have not been doing anything out of the ordinary and really have no explanation for her recent behavior. 
Tomorrow, I plan on buying her a new and bigger Litter box and reverting the litter brand back to the one I used to get her as a kitten. 
If you brave souls who have read through my desperate plea have an wisdom to offer, be it from experience or not, I would be eternally grateful.

Can you give me a shortened version of the text?
