My cat has a problem with the litter box

Besides giving your cat a choice of several litter boxes ( try Scoop Away for Multiple Cats ) , get Natures Miracle Enzyme spray to spray the spots on the concrete…it will deorderize and remove the stain…it might take a few sprays if the stain is heavy. If there is a mess, pour litter on it…to dry it quickly…so it doesn’t set in.

Harleyrider is right. Some cats prefer one litter box for peeing, and another for pooping. So maybe you need to get another litter box for this cat for pooping. To train him/her to use it, leave a bit of his/her poop in the new box so that it will get the idea that it’s HIS/HER pooping box.

Hmm try putting newspaper on the ground, as for how to solve it, I dunno my cat does the same thing

they do say that for two cats you should have two liter boxes plus one. so maybe have three liter boxes. and make sure they are always cleaned out

Cats are very private about peeing in the same litter box, if she keeps doing this its because she or he dosnt like the fact that the other cat is doing is stuff in its bathroom… I would say you should get another litter box and they will work things out.

Cats are really clean animals and they do not like a dirty litter box - at all, so you’ve got to keep clean on a daily basis. The idea of three litter boxes is good. Many animals mark their territory with their urine, and the cats may be “remarking” the territory to cover the others scent. But when they are pooping they go to a “clean” spot to do it.

Try chlorine bleach on the stains, but I’d test it first, a small patch somewhere unnoticeable. It sounds like the concrete is not sealed and it might bleach the spot white and make white spots instead of brown ones.
