Can Cat Litter Really Cure Motorhome Damp? Myths Expelled!

Can you use cat litter as a moisture absorber for damp in a motorhome or caravan

Rice as wedding confetti, heated wheat as muscle relaxant and banana skins as shoe polish. What next? Corn Flakes as loft insulation and baked beans as an alternative to diesel? We’ve all heard these slightly surrealistic uses of substances for our mundane tasks. High in on that seemingly daft list is the use of bowls of cat litter as a dehumidifier. The thing is there’s actually an element of easy logic to this one…

Cat litter is sometimes offered as a tip for anyone with moisture removal problems – it’s fairly obvious when you have even only a rudimentary grasp of the science. But, actually, just investing in BirchSorb would give you a superior solution and an easier experience. It was designed to be the best on all fronts. So what makes it so?

To explain, in this edition of our blog we have a look at both, and work out their benefits. Let’s begin, though, by getting happy thinking about cats…



Domesticated cats make great pets. These feline friends are beautiful (even when they’re actually not), full of character and fun – and they compel owners to do their bidding. This can include some fairly unpleasant tasks. For instance, changing the cat litter regularly. 

Cat litter comes in several forms – most often either clay, woodchip or silica gel. Litter soaks up a cat’s toilet waste, and keeps their tray clean for a period of time anywhere between a few days and a few weeks. This is usually dependent on the type you use and whether you maintain it properly.

So, bearing in mind the decent absorption properties of cat litter, it follows that certain types of it could be used in other environments where the removal of moisture is highly desirable. But is cat litter truly practical and effective in other scenarios?


What is clay cat litter?

Clay cat litter is probably the most popular choice amongst cat owners. It’s cheap and it’s certainly the easiest to come by. Any supermarket or corner shop you visit to buy some is likely to stock clay cat litter rather than other types. This litter is made up of very small pieces of dried clay which absorb moisture and turn into a substance a little like soft cement. It’s effective but not perfect, as clay rereleases moisture - though it does the job as far as your cat is concerned.

In other scenarios, though, despite the fact clay cat litter will absorb some moisture from the environment there are always dangers attached.

Imagine you’re looking into damp solutions for motorhomes. You could decide on cat litter and use a couple of bowls of it on the floor or work surfaces within your mobile home. What happens if you accidentally knock or kick over the bowl? Spills could also be caused by the motion of your vehicle. You’ll end up not just dealing with the initial issue of damp in your motorhome but yet more problems which would be difficult and time consuming to sort out - including irritating small pieces of that cement-like substance causing unsightly stains to your carpets or upholstery.

As well as preventing damp in motorhomes there’s also the unlikely but possible other issue of your vehicle suddenly becoming popular with strays who are looking for somewhere to pee!


What is woodchip cat litter?

Increasingly popular, this type of cat litter is made from pellets of wood which have been formed into small cylinder-shaped pieces. This means it’s relatively lightweight and is also more environmentally friendly than clay litter. It’s good for odour control and quite cost effective as it’s cheaper than other types.

In domestic scenarios other than cat litter trays, it’s not hugely effective due to the sheer bulk of the amount you’d need to deal with moisture situations and, as with clay litter, the problems caused by any spillages or loose pieces.


What is silica gel cat litter?

Silica litter is completely different to woodchip or clay litters. Made of silica dioxide sand, oxygen and water, it looks like small crystals. Silica absorbs around 27% of its own weight but becomes obsolete quickly, though. In moisture removal scenarios outside of the cat litter tray it’s not the most effective solution – again, in part due to the likelihood of spillages and mess.


Why BirchSorb is best! 

A huge starting point for singing the praises of BirchSorb over clay, woodchip and silica gel cat litters is the lack of mess. All of them work to some degree (though none is as effective as BirchSorb), but each of them also comes with some sort of after-problem to be dealt with.

BirchSorb does not. There’s no need for any cleaning up of bowls or containers of this or that, and any additional mess that they will probably have generated. BirchSorb’s highly convenient packaging is very tidy and incredibly easy to use. Without much effort at all you can use it in your leisure vehicle, home, garage, shed, shop, storage facility, library or work premises. It’s fuss free and mess free and works hard to keep you damp free! 


That’s the packaging, then, but how does BirchSorb do it?

During lime production,  our scientists discovered a molecule which is incredibly effective at drawing in moisture. They created an exclusive formula from it, and this was developed into the product BirchSorb.

A BirchSorb unit sets the moisture it has collected into a solid form. The unique blend of multiple active ingredients mean the moisture is chemically ‘bound’ during an exchange between the fast and slow acting components of the formula. There is no subsequent spill, leakage or re-release over the minimum eight weeks of a BirchSorb unit’s life. Also, it can ‘handle’ at least 200% of its own weight. Impressive! 

Keep the cat litter exclusive to the cat litter tray and invest in BirchSorb if you want a convenient and highly effective moisture solution. It was designed for that. We say: Spend more time worshipping your cat (also designed for that) than cleaning up cat litter, whatever the scenario!
