In case you’re contemplating including a four-footed companion to your loved ones, you may be questioning about your future buddy’s potential environmental influence — particularly if cats are simpler on the earth than their canine sidekicks. As a cat proprietor, I’ve puzzled this myself! The reply relies upon largely on the dimensions of the animal and the way a lot they eat. Giant canines comparable to German Shepherds require considerably extra meals than smaller breeds like Chihuahuas.

Giant canines are at all times worse for the atmosphere than smaller canines or cats in relation to food-production-associated environmental burdens. However once you issue within the environmental prices associated to the manufacturing and disposal of kitty litter, canines who weigh lower than 10 kilos or so could also be higher for the atmosphere than equally sized cats. Include me as I stroll you thru the main points:

Why Does the Quantity Canine and Cats Eat Matter?

An excessive amount of the injury we do to the earth is instantly associated to the manufacturing and consumption of meals, meat specifically. The extra meat a cat or canine eats, the larger their carbon footprint, making an animal’s measurement essential in relation to figuring out their environmental influence.

However let’s begin at first—with vegetable and cereal farming. All farming has an environmental influence, even after we develop fruit and veggies utilizing natural ideas. (Natural farming typically requires tons of land.)

Attributable to fashionable farming’s excessive manufacturing calls for and customers’ aesthetic preferences, producers typically flip to pesticides and fertilizers to guard and enhance harvests. Many of those chemical substances trigger severe environmental injury as they accumulate within the soil and contaminate water sources.

Then there are the greenhouse emissions associated to the bodily actions concerned in farming—assume operating equipment and transporting merchandise. And don’t overlook to think about every thing concerned in producing and delivering even essentially the most primary packaging.

Meat manufacturing is a spectacularly inefficient technique to produce meals as this course of primarily will get repeated twice earlier than you should buy a bag of kibble. Research point out that pound for pound, farming simply 1 pound of beef releases the identical quantity of carbon dioxide into the environment as producing 15 kilos of rice or 60 kilos of corn, peas or wheat.

Put one other means, producing 1 kilogram of hen requires roughly 43.3 sq. meters of land. (Beef and lamb require way over that!) A complete kilogram of grain, then again, solely calls for a mere 13.4 sq. meters of land.

Meat manufacturing is problematic for different causes as effectively, together with the methane gasoline produced by ruminants like cows. The rumen is a particular abdomen compartment current in lots of grazing mammals. It’s the place meals that hasn’t been fully digested is saved and begins to ferment earlier than being despatched to the opposite elements of the abdomen to be damaged down and absorbed. Methane gasoline is produced throughout this fermentation course of. However methane soaks up atmospheric warmth like there’s no tomorrow. In accordance with the MIT Local weather Portal, methane gasoline “traps round 100 instances as a lot warmth as carbon dioxide.

What Does This Imply in Actual Phrases?

In 2009, Barbara and Robert Vale, professors who examine sustainable constructing and educate at Victoria College of Wellington, printed a e-book through which they crunch the numbers relating to the adverse environmental influence of pet possession — Time to Eat the Canine: The Actual Information to Sustainable Residing. Their conclusions have been surprising.

The typical medium-sized canine apparently eats about 164 kilograms of meat and 95 kilograms of grain per 12 months. After factoring within the quantity of land wanted to supply hen and numerous grains, the Vales calculated it requires roughly .84 hectares of land to feed a canine the dimensions of a Labrador Receiver. You solely want round .41 hectares of land to supply sufficient power to drive a Toyota Land Cruiser 10,000 miles.

Cats are smaller and require far much less meals than the common canine, however they’re not precisely environmentally pleasant! Feeding only one cat requires .15 hectares of land, only a bit lower than you’d have to hold a Volkswagen Golf up and operating for a 12 months.

A more moderen examine printed in PLOS One reached comparable conclusions whereas describing the phenomena a bit in another way. After tapping the American Kennel Affiliation for details about the ten hottest canine breeds, Gregory Orkin, creator of this progressive 2019 examine, averaged their weights. In accordance with Orkin’s calculations, the common canine in the USA weighs 22 kilos, greater than the common cat who suggestions the scales at 10 kilos. Canine require 544 kJ (kg BW)-0.75 d-1 of power to outlive. The corresponding quantity for cats is 544 kJ (kg BW)-0.67 d-1.

Attributable to weight variations, the environmental influence of feeding the common pet cat is decrease than that concerned in retaining a mean canine correctly fed. When weight and inhabitants numbers are factored collectively, US canines eat way over US cats.

Companion animal possession has severe environmental penalties—cats and canines collectively eat round 24% of all of the animal-based power consumed within the US or about one-third  of the meat eaten within the nation. These numbers might sound exaggerated till you notice that round 70% of US households have no less than one pet—there’re round 69 million houses with pet canines and 45.3 million houses with cats.

The USA has the most important companion animal inhabitants on this planet. And we may feed round 62 million folks with the meals and power that goes into meals manufacturing for US pets.

And issues will most likely worsen as worldwide developments in pet possession proceed. Whereas companion pets have been widespread in North America, Europe, and Australia for many years, the apply is turning into more and more widespread in growing and middle-income nations. Because the variety of companion animals saved in houses around the globe will increase, so too will the magnitude of those animals’ environmental influence.

There additionally seems to be a shift in values underway, altering the way in which many consider cats and canines. In accordance with Orkin, the humanization of companion animals may very well spur extra environmental destruction as pet house owners start demanding higher-quality cuts of meat for his or her cats and canines.

What About Poop and Kitty Litter?

Our animal companions aren’t doing us any favors within the poop division, both. The common human poops out about 0.147 kg capita-1 d-1. That quantity is round 0.042 kg cat-1 d-1 for cats and 0.15± 0.07 kg canine-1 d-1 for canines. Cats are likely to weigh a lot lower than canines and due to this fact produce much less waste on common.

Canine and cats collectively are chargeable for about 23% of all poop excreted within the US—people are chargeable for the remaining. Companion canines and cats produce as a lot waste because the human inhabitants of a state across the measurement of Massachusetts, most of which leads to landfills the place it decomposes, releasing methanea serious contributor to world warming—into the environment.

After which you have got the environmental influence of all that kitty litter. Sadly, most research evaluating the environmental influence of pet possession solely think about the results of feeding companion animals, failing to account for elements comparable to the prices of manufacturing and disposing of kitty litter, that are fairly substantial when you think about the harms attributable to strip mining for clay, the sources expended within the packaging and transporting of litter associated merchandise and the contribution non-biodegradable litter makes to our rising landfills.

Clay and silica/crystal-based litters are merely not biodegradable, placing most cat house owners within the disagreeable place of including to landfill waste and contributing to world warming every time they alter their cat’s litter.

There are a number of methods to get began for those who’re severe about lowering your cat’s environmental influence. One is tremendous easy—the others require a bit extra dedication and planning. The quickest and best technique to cut back your cat’s environmental influence is to make use of biodegradable baggage to eliminate waste once you clear or change the litter. You’ll be able to simply discover small biodegradable poop-disposal baggies at most grocery shops. And there are tons of biodegradable trash baggage and cat pan liners to select from.

Switching to biodegradable litter is a extra concerned choice, however it may be a fantastic selection when you’ve got the curiosity, the cash and your cat tolerates the change. There are tons of biodegradable choices in the marketplace produced from sustainable merchandise comparable to recycled newspapers, dried tofu and wooden chips. There are clumping and non-clumping varieties in addition to fragranced and unscented decisions. You’ll be able to even compost un-peed or pooped on elements of used litter to significantly restrict any cat-related landfill contributions. Simply bear in mind to solely sprinkle compost with cat litter on nonedible vegetation.

In case you’re actually severe about minimizing your cat’s environmental footprint, think about buying pet meals from an organization that explicitly elements the safety of the earth into its enterprise mannequin. There are a number of pet meals makers, comparable to Open Farm, that adhere to sturdy sustainability and transparency requirements and others, comparable to The Sincere Kitchen, that function as B firms pledged to issue components comparable to sustainability and justice into their enterprise fashions.

And carbon offsets are a considerate and tremendous sensible technique to give only a bit to the world and to thank the earth (and your fellow human beings) for the privilege of welcoming a furry companion into your life. (Right here’s a hyperlink to an article with a number of tips about discover a respected carbon offset program that aligns along with your values).


Cats are typically higher for the atmosphere than canines in relation to the most important offender — meals manufacturing. As a result of cats are smaller than most canines and due to this fact usually eat much less meals and produce much less poop, cats have much less of a adverse influence on the atmosphere than canines. That’s nice information for those who love cats as a lot as I do!

However then there’s the nightmare that’s kitty litter, with its problematic connections to strip mining and preponderance of non-biodegradable elements, making it unimaginable to say cat possession is something near earth-friendly. Utilizing biodegradable kitty litter, buying cat meals and treats from corporations that function in line with sound sustainability ideas and investing within the occasional carbon offset can go a good distance in the direction of lowering the adverse influence cat possession has on the atmosphere.
