Siamese Cat behavior

Question
My cat was fine until about December of last year, when i started moving around a lot. She is constantly peeing on anything, and everything. She is worse about it when she is in heat.  At the beginning of Jan. She lived at my mom's house with 1 other indoor cat, 3 dogs, and 2 farrets, and didn't pee that much after a while. This is when she started peeing,at my mom's. I then moved to an apartment with my bf and she got a little bit better. We also got another kitten, that is now 6 months old, that she was fine with. They would play around together. Then he left to go into the military and i am back at my mom's with my two cats, and her animals for at least a year. She is awful now about peeing everywhere and i do not know what to do. Should I get her fixed and it maybe solve the situation a little, or is there something else I should do? She is a loving cat when she wants to be, and i do not want to get rid of her. Please help me try to solve my situation. It would be greatly appreciated.

Answer
Melissa,
First...YES, get her spayed.  Get all of them spayed.  Cats and dogs are much healthier and happier when they have been fixed.  This will avoid lots of problems not to mention unwanted babies.  It could help this peeing problem too, but probably not completely.  Cats show stress by peeing in odd places.  She is doing this because the move and new situation has stressed her.  First have her spayed.  Then, any place she has peed, clean with a carpet shampoo solution made specifically for "animal accidents"  or add some white vinegar to regular carpet shampoo.  This will get rid of the urine odor so that the cat can't smell it.  Just because you can't ,  doesn't mean she can't.   After cleaning all areas,  confine her to a small room when you're aren't there,  with her litter box.  When she has free roam of the house,  watch her!!  If she goes outside of her litter box, then lightly scold her,  but not intensely, as this will only make it worse, then take her to her litter box.   Beating or rubbing cat's nose into the accident just does not work, so please don't do it.
I hope this helps.  Good luck.
