Why is my cat peeing under the litter box? Is the box too small?

Updated On September 23rd, 2025

I have adopted 6 stray cats and they have been with me for the last 1 year. They have well settled in. One of them, I don't know who has been pissing outside the litter box( not around the house or anywhere) urine is always found under the litter box. They are all 2 years old, spayed and litter trained. Is the litter box small for them? 3 male, 3 female. Litter box is fine. Urine is under the litter box. Attaching pics.

I would try a large litter box. Some cats, especially males, need a large space in order to not accidently drip on the outside of the box. You may also try the option of a covered box. Some cats don't like those so I would still leave out the uncovered boxes. You could also get some of the urinary pads like puppy pads or geriatric human bed pads to put under the pans to make clean up easier. Finally, I would make sure you have enough boxes in general. The typical rule of thumb is a litterbox per cat plus one extra. I know with 6 cats, that can be a lot so however many you can put throughout your house, the better. I hope this helps!
