<human>: Hey guys, first I will introduce Chloe, I 'acquired' Chloe when her irresponsible owner decided to have her put down when she couldn't have a cat in her new home. (WTF man?!) Chloe was ~5 years old at the time.

Around then I was living with a friend and his dog (friendly) and my one cat. The plan was to find Chloe a new home, however it is very hard to find a home for a grown cat. Chloe had no problems at the time, was healthy but not friendly with other cat or dog. she did her own thing and tolerated the others.

Fast forward a couple years and Chloe is living with my mother and (was) doing fine for quite some time.  Lately, Chloe has been having some altercations with the neighbours cats (who are dicks!) and she started peeing inside, much to my mothers' frustration, in fact she is so fed up with it that I need to do something about Chloe within the week.

Chloe has been checked numerous times for UTIs and come up clean. I believe she is under stress from the other cats and I am looking for ways to mitigate this.

I am still unable to find her a new home and as a last resort, there is a rescue facility called Cat Haven, they can take her in and hopefully find her a home but they're volunteer and donation based so again, a last resort.

I probably have answered my own questions here (shelter surrender) but I want what's best for Chloe within reason.

Could you distill the essence of the text into 1-3 sentences?
<bot>: female cat pees inside due to stress from other animals, want to stop peeing or move her to a shelter.
