How do you remove a litterbox?

First off you need to clean the area with a very good enzyme cleaner (I recommend Anti-Icky-Poo or Nok-out... IMO Nature's Miracle is just not strong enough....) Then I would put a Litter box in there, and start moving the litter box from there very slowly, a little bit every day, until you get it on the new location. It will take a couple or a few weeks to move completely, but this way the cats will follow the litter box... Good Luck!

Wood is porous, you can't soak or scrub anything out of the wood itself without the risk of damaging the wood and especially the finish. You'll have to sand and reseal it.

The only time I've move boxes is when it's only a few feet

Never put use any sort of cleaner on a hardwood floor that isn't specifically meant for cleaning finished wood. Anything else runs the risk of discoloring the wood (baking soda can turn wood black for example, other cleaners can bleach the wood or ruin the finish). Depending on the finish, it will react very differently to being wet to begin with.

If you can, you may want to consult a professional wood floor refinisher and ask for advice and about refinishing your floor - chances are if the urine penetrated to the wood in the first place that your finish is worn/damaged and needs to be redone.

What kind of litter box do you have?

Is that the only litter box?

How many cats use it?

How often do you clean it out?

Have you thought about trying a hooded litterbox? - the extra large size? Over the years I've found that some cats are better than others at keeping their bottom inside the box when doing their business. I found that a large hooded litterbox was the answer.

What type of flooring do you have there?

Is it just a case of them miscalculating where their bottom end is while doing their business; such that it's hanging over the edge of the box -- or are they actually doing their business outside of the box, directly onto the floor?

Can food/water bowls be temporarily moved to the area? But I'm not sure if that would work - your cats might go on a hunger strike

Ahh, so it's not a problem of poor aim; it's due to the urine having soaked into the wood, they pick up the scent of it (even though you may not) and they return to pee there.

Have you considered putting another litterbox RIGHT beside the existing one; side by side....so that the entire "area" is covered with litterboxes?

Are you able to move the box to a different area of the room....then totally cover up this area with something (not a mat or something that can be peed on); a cabinet, or some type of large object that that will completely cover this area.......?

I'd do as others suggested, too. Contact a flooring place, have someone come out and give you an estimate on sanding down the area....restaining then sealing with varathane........?

Not trying to be critical here, 5 cats is a lot of poop and scooping, but this could be the problem, that you only clean it every couple of days.

Cats are very clean creatures and don't like to have to walk, dig around in a litter box that is not clean. In fact most cats tend to "fly" out of the box once they have given a "gift" just because they don't want their paws touching it! And some cats don't like to pee and poop in the same box!

Think of it this way, when you walk into a public restroom and the stall you walk into has not been flushed, what is your reaction? "eeuww!!!" and quickly find another stall. Or when you walk into a stall that still has a lingering odor, isn't it the same thing? I know I try to find another stall when that happens . That's why I don't like covered litter boxes as they tend to keep the smells in.

Just because they are cats doesn't mean that the smell of their buddies poops doesn't bother them My cats, Rascal, does not like to cover his poops after he is done. You can be sure that if I'm not around to scoop it right away, Samson will quickly run over and cover up the offending smelly poop himself and he doesn't look too happy about it!

You may have to move that litter box from that area completely though.

You may have to add a second litter box where they can use it just for peeing. Also have you tried Cat Attract? I've never used it myself, but I hear it can work well.

Good luck and please keep us posted!
