cat peeing out side of box
I have owned cats for years and have worked with this problem a lot.
over and over when a cat starts this out of the box peeing it is because they do not like the cat box,or where the box is located or they are stressed out by not being able to get up high above or be able to position themselves in the house where they otherwise feel safe.
CAT BOX: they may not like the conditon: dirty, or the litter smell or dust, or they need one for Pee one for Poo, or they do not like the design--the lid or hood. TRY: taking the hood off, this helps be able to clean it more often. thinking about the type of litter used.
Where the box is located: is it somewhere they feel ambushed to go in or to come out? does the other cat bother her "in there" is the location noisy or so out of the way she feels bothered about getting to it? does she have to get past the other cat to get there or get past someone who always gives too much attention to her?
Safe place cats need to be able to get up high for their feeling of wellbeing. does she have a cat tree or a place to jump up and look down? or a place she can hide away from everyone or also get away from other cat and also most important if not up high can she see people or things comming?
Misc Cats also tend to like to pee on dirty clothes piled on the floor. putting clothes into a "hamper" solves this.
PunnishmentCats do not understand the nose in pee and spanking or loud no etc--better_ get a catbox, lid off, in new place and randomly place her in it at calm times. she may get rite out, but keep bringing her there. cats love the ease of getting in and out and cannot resist loose dirt.
PS my own favorite is called a Jump down box it is deep enough to use lid off or jump down. also at home fixit stores get a storage type of box and use that the edges are high.
