Cats and the Environment I: The Litter Question

I was talking to my boss last week about her cats. It was originally a discussion about the composter I want to buy (which she has and likes [though she says it does smell a bit when you open it]), but grew into a discussion of recycling here in the office and at home and that led to the thing I do that annoys me most, ecologically speaking: throwing out the cat litter.

We have two cats, both indoor-exclusive, and we live in a condo high-rise with some very strict rules. One of them is that you must not toss bags of kitty litter down the trash chute. (That's pretty common sense, actually--bags do not stay intact while hurtling 30 floors through a small tube to their death in the garbage room, no matter what anyone tells you. Litter Bomb? No thanks.) The building's answer is to do a daily trash run: kitty litter bags are left in the trash room on our floor and maintenance comes by in the freight elevator and adds it to the pile of kitty litter bags they already have. It cuts down on the possibility of a litter bomb, so this rule, too, is all to the good.

Not to the good? I cannot reuse plastic grocery sacks to bag the litter. And it must be double bagged. So I end up spending extra money to buy small trash bags and then double wrap the kitty litter to ensure that it never ever sees a molecule of oxygen with which to decompose.

Annoying. And again, I mention that we have two cats. Who create a lot of smelly litter. In a high-rise building with decent but not brilliant cross-ventilation, I have to scoop the litter boxes (plural) every single day and still there is the problem of a teensy bit of stink in my oh-so-sensitive nose. Baking soda mixed into the litter helps, but the odor isn't the only problem.

I have allergies. Big, bad, killer allergies. And every single day, scooping that clay clumping litter is killing my lungs a little bit more. Yes, I know that there has never been a clinical study that shows that clumping litter is dangerous for anyone's health (but I kind of think that's just because they haven't bothered to study it), but the fact remains that I kick up an awful lot of dust scooping those things out and that does my allergies no good at all--can't imagine burying in the dust is great for the cats, come to think of it.

And the creation of the litter does no good to the earth, either. Conventional cat litters use clay, which is usually found some 30-40 feet underground on clay-containing mountainsides. Easiest way to get to it? Skim off the 30-40 feet of topsoil and growth above it and collect the clay. The result is a lopped-off mountainside (we had one where I was a kid--they're finally rehabilitating it now, decades later) that increases flood damage for the land below it and is generally an ecological disaster. It is so time for a change.

At first blush, biodegradable cat litters look like a fine idea. They are often made from things like leftover pine branches after a tree has been felled by the lumber companies or from corn husks and cobs left over from grain extraction (not 100% green, but at least it uses up the stuff no one wants). They rarely have anything chemical added to them and are, by all accounts, very good at controlling odors. And they biodegrade! They break down when you're done with them! Sounds perfect.

In actual fact, they are brilliant for people who have outside composters or large compost heaps that generate enough heat to kill all the bacteria that teem through feline waste. For someone like me--who will be double-bagging the dang stuff in air-blocking plastic, so it can be thrown in a landfill, which is, itself, an almost completely anaerobic environment--biodegradable litter only provides me with a product that was slightly less earth-killing to produce.

Flushable litters offer a good solution for me. There are a number of organic and/or natural brands out there, with varying textures, so moving your cat from one cat litter to another might be a little easier if the two feel basically the same. They don't really cost any more than the clays and might actually be more cost effective because you use less of them (supposedly--we'll see what happens in Chez Peaceable).

The basic truth is that I don't have a properly ventilated space for a certified animal-waste-processing composter (they suggest these only be placed outside because they smell regardless), and I'm sick to death of A) having to take my litter out to the trash room at a specific time to make sure it doesn't smell up the hall while it's waiting to be picked up, and B) throwing away hundreds of pounds of earth-damaging clay litter. I'm just starting my first foray into trying to get my older cat to use it. This should be fun.

NOTE FOR OWNERS OF OUTDOOR CATS: If you have an indoor-outdoor or outdoor-exclusive cat, your animal may be exposed to toxoplasmosis, a parasite which is not fun--it is the reason why pregnant women are told not to clean cat boxes, because the risk to the fetus if the mother contracts toxo is very, very high.

For this reason, you should probably find a different way to dispose of your kitty litter than flushing it down the toilet. Regional water treatment plants don't screen for toxo and it could end up in the water supply or, more likely, in the lakes, rivers, and oceans. Composting is the best bet there, as the heat of composting should kill off the parasite. Also, taking your cat to the vet and having them tested for toxo periodically is a healthy thing to do anyway. If you or your partner is pregnant or plans to become pregnant, for the love of the unborn babies, please test your cat for toxo. Birth defects are bad.
