Update there was 1 weekend we had left for a trip that our cat peed on a bunch of stuff. But since then we have had 2 other trips and no pee anywhere! Looks like all it took was an uncovered litter box.
To answer your questions for others who may run into this problem.
-She is spayed.
-She has no problem controlling her bladder when she sleeps (considering we haven't found pee in any places she loves to sleep)
-Our vet says she probably just has anxiety.
-Also we have been using Natures...
To give Y'all as much info as possible:
My GF and I adopted a cat who had been in the shelter for nearly a year and was 3 years old. She is an absolute sweetheart so about a year after that we adopted a second cat the day it was supposed to be put down by the shelter. We separated the 2 cats...
