How Often Do You Clean The Cat Litter?

Be honest, how often do you clean your cat’s litter tray? You have to be honest, now. Is your cat walking on used cat litter sometimes?

I clean the cat litter once per day. That was when my late lady cat used the litter. She used the litter tray about twice per day. Once for a pee and once for defecation. Although later on she peed more often during the day. When that happened I should have made it a routine to clean the tray more than once per day. I did occasionally. At the time, I felt that was OK but…ideally I now feel that I should clean the tray after use so that when it is reused it is totally clean. Do you think that way? Can you achieve that? You may not be able to because you are out all day, most days.

The Wild Cats: In the wild, wild cats sometimes do have toilet areas but they are much larger than a litter tray. They are not going to use the same spot each time. It is the size of the tray that is confining.


Michael J. Fox, a well known vet and author says:

“The litter box should be cleaned three to four times daily, and fresh litter put in to replace the soiled litter as needed…”

This is incorrect, really, because if you have one cat and that cat uses the tray once per day it is pointless cleaning it four times. However, he makes a good and strong point.

The point he is making is that when we go to the toilet in our bathroom we expect the previous user, which might have been us, to have flushed it! We don’t expect to have to flush the toilet first. That would be considered disgusting. Yet there are many cat owners who expect their cats to accept that situation and worse, because they can’t flush it away! And we know how fastidiously clean cats are.

I wonder how they feel walking on their own pee and poo? Or worse still in households where there is more than one cat walking over another cat’s pee. It may be that he does not like the other cat and we know that pee is heavily scented. Cats are very sensitive to scent. This is the sort of scenario where a cat could become stressed.

There are also the health risks. A cat walking on another cat’s poo is likely to ingest it afterward when he licks his paws clean. This is a way diseases are transmitted (i.e. toxoplasmosis)

The point that I think is worth making is that there is a tendency to get a bit casual about cat litter. And I am not being critical of anyone. In multi-cat households, and there are lots of households with two cats, the work load in cat litter cleaning duties mounts considerably. There is an argument that there should be one litter tray per cat. I doubt whether many people follow this rule or suggestion.

Bearing in mind how clean cats like to be and how sensitive to scent they are, it would seem fair and proper that we clean the cat litter tray after each use and present our cat with clean litter every time he or she uses it. That is the target. I wonder how often that simple target is met in households across North America, Great Britain and elsewhere?

One of the most prominent cat behavior problems is “inappropriate elimination”. I actually dislike that often used phrase because for the cat it is appropriate to eliminate outside the litter for whatever reason and one good reason is that the litter is dirty. Persian cats are particularly sensitive to this. Some individual cats of any breed or randomly bred will be sensitive too.

Often “inappropriate elimination” could be re-written “inappropriate litter”

  1. Bigfoot is free to go outside, but he chooses to use his own litter. He sometimes comes running in fast, up the stairs jumps in his litter tray…then goes back outside. Makes me scratch my head in wonder. He is odd on many fronts. I love him anyway.

  2. Love it. These days I don’t do it at all as Charlie goes in the garden. He always has it seems. I wonder if some indooor/outdoor cats use a litter tray or whether they all use what is natural outside.

  3. That is certainly a preference for cats. Except for Bigfoot. I still wonder where Marvin goes. He’s very private about it. I may never know! Yellow cat loves the foot-deep fallen oak leave bed out back. Shadow likes the dirt pile behind the vegetable garden. Thank goodness not in the tomato garden!

  4. Hmmm, about once every six months as that’s about how often one or the other of our boys use a tray, the rest of the time they go happily off to answer the call of nature outside in their own litle latrine corner.
