My cat poops everywhere but the litter box
I adopted my cat when she was 3 months old. I actually rescued her.
At the beginning she did not pee or poop in her box and did not poop for a very long time. I took her to the vet and they said she was constipated and gave me laxatives which worked.
Although she started pooping since I have had her, for the last 4 months she only pees in the box, never poops.
I have tried everything... new box, bigger box, different litter, big/small, mixed dirt with the litter to make it softer, but she has taken a love for my bed and that is killing me.
She is also going to new places in the house to poop but never her box. I have washed everything with vinegar, put lavender to repel her, used a scent to make her box more attractive, but nothing.
I put her food in my bed, someone told me that cats don't poop where they eat but she did, and is starting to poop again despite the lavender, so please help.
I have taken her to the vet and fixed every problem they thought was the cause, and nothing.
My thoughts: Assuming she has no health problems, it may be effective to put her in a situation where she has fewer options.
If she were my cat, and I had tried many other methods, I'd think about confinement retraining. Also called isolation retraining, I've written about this many times as a solution for extreme cases.
In shelters, they often place cats in large cages, along with a litter box and water and food. In that situation, the cat has very little choice but to use the box.
If a cage seems too extreme, you could try confining her to a single room instead.
Once she's on track with her box habits, she can be allowed the freedom to explore the rest of the house.
You could also try Cat Attract in the litter and a Feliway plugin diffuser.
I hope that helps. Please let us know how it goes.
