Change in environment
Have you changed something in your home? Maybe you got new furniture or got rid of something they loved? Did someone leave the home? Maybe to go to college or because of separation?
These are all changes that can affect a cat. Many cats tend to brush things off however a few cats do respond poorly to change. If you think this is why your cat is acting anxious you may want to spend a bit more time with them and/or get them a new fun toy to play with.
A new addition to home
Your cat may be anxious because you have a new addition to your home. Did you recently have a new baby or bring in a new pet? Your cat will respond to this and sometimes severely.
You may want to plan when you have a new person or pet coming into your home. Find a place for your cat to retreat so they can relax. You can also provide cat trees and scratching posts to help calm them.
Moving
If you have recently moved, your cat may just be responding to the change. You will want to ensure the cat is comfortable in their new home. Bring out a box of old toys for them to play with. Allow them to explore the house and find familiar items to put out quickly so they can have the smells they recognize.

Boredom
Your cat may just be bored. If you work outside your home all day and have an energetic cat, you may find that they miss you and need more stimulation.

You could also consider getting another cat if you don’t already have one. What you need to remember, however, is that this could cause more anxiety in your cat so you will want to consider your cats personality before bringing in a new friend.

A Dirty Litterbox
Do you clean your litterbox daily? If you don’t, it’s not just you. I can’t do it every day, either. However, a dirty litterbox may be the reason your cat is pooping in the tub and not in its litterbox. If you notice they use it only after cleaning it, you may want to start cleaning it more often.
You can also invest in a self-cleaning litterbox. A few years ago, I invested in a Litter-Robot, and though Pumpkin is still not using it at the time of writing this, my other cat Dixie loves it, and I love that I don’t have to scoop litter anymore.

Location of Litterbox
The litterbox is next to their food
Cats do not like having their litter box near their food. Think about how you would feel if you had to eat every meal in your bathroom.
I made the mistake of doing this once with my last cat. She never went outside of the litterbox. However, one day while I was still living with my mother, I was cleaning my bedroom. I temporarily moved the food dish next to the litter box to clean it. My mother came up, and we started talking. The next thing we knew, my cat came out in the hall, meowed at us, and peed on the floor.
This event caused me to look at why a cat would pee on the floor, and that is when I found out about the litter box near the food issue I realized that was the problem and fixed it. If you have all of your cat’s things in one spot of your home, you may want to look at moving either the litter box or food to a new area.
The litterbox is in a highly trafficked area
Your cat may just want some privacy when they use the litterbox. If you have your litterbox in an area where many people walk through or hang out, you may want to move it.
This is not always possible. If you live in an apartment, as I do, there is no place to put a litterbox. The good news is you can find some fantastic litterbox furniture on Chewy.com That will cover your litterbox and give your cat the privacy it craves.
Your Cat Hates the Litter You Use
Did you recently switch litter? Your cat may just hate the new litter. Cats are picky animals, and they sometimes have issues with the way things feel on their paws, the smell, or if it’s clumping litter or not.
Try out a couple of different types of litter at once. See what box your cat uses, and then you have the answer and the litter that will make your cat stop pooping in your tub or sink.

You don’t have enough litter boxes
Did you know that you should have a litter box for each cat you own, plus one more? This may come as a surprise to you, but it did to me when I started researching. I have two cats, so I got three litter boxes. This, unfortunately, did not solve my problem, but he would use the litterbox more often.
You may also not have enough litterboxes around your home. You may not think it’s an issue for your cat, but if you have a large house, you will want to put litterboxes in different areas. Make sure there is one on each floor, or if your home is long, one on each side of the house if you can’t put them somewhere in the middle.
Having cat poop outside of the litter box is annoying and frustrating. However, with a few simple tips, you should be able to get your cat back to using the litterbox and out of your tub or sink.
