In case you’re contemplating including a four-footed companion to your loved ones, you could be questioning about your future buddy’s potential environmental affect — particularly if cats are simpler on the earth than their canine sidekicks. As a cat proprietor, I’ve questioned this myself! The reply relies upon largely on the scale of the animal and the way a lot they eat. Giant canine equivalent to German Shepherds require considerably extra meals than smaller breeds like Chihuahuas.
Giant canine are all the time worse for the setting than smaller canine or cats in the case of food-production-associated environmental burdens. However once you issue within the environmental prices associated to the manufacturing and disposal of kitty litter, canine who weigh lower than 10 kilos or so could also be higher for the setting than equally sized cats. Include me as I stroll you thru the small print:
Why Does the Quantity Canines and Cats Eat Matter?
A substantial amount of the harm 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 better their carbon footprint, making an animal’s measurement essential in the case of figuring out their environmental impact.
However let’s begin firstly—with vegetable and cereal farming. All farming has an environmental affect, even once we develop vegatables and fruits utilizing natural ideas. (Natural farming typically requires tons of land.)
On account of fashionable farming’s excessive manufacturing calls for and shoppers’ aesthetic preferences, producers typically flip to pesticides and fertilizers to guard and enhance harvests. Many of those chemical substances trigger critical environmental harm as they accumulate within the soil and contaminate water sources.
Then there are the greenhouse emissions associated to the bodily actions concerned in farming—suppose operating equipment and transporting merchandise. And don’t neglect to consider all the things concerned in producing and delivering even essentially the most fundamental packaging.
Meat manufacturing is a spectacularly inefficient technique to produce meals as this course of basically will get repeated twice earlier than you should purchase 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 chicken requires roughly 43.3 sq. meters of land. (Beef and lamb require excess of that!) An entire kilogram of grain, however, solely calls for a mere 13.4 sq. meters of land.
Meat manufacturing is problematic for different causes as effectively, together with the methane fuel produced by ruminants like cows. The rumen is a special stomach compartment current in lots of grazing mammals. It’s the place meals that hasn’t been utterly digested is saved and begins to ferment earlier than being despatched to the opposite components of the abdomen to be damaged down and absorbed. Methane fuel is produced throughout this fermentation course of. However methane soaks up atmospheric warmth like there’s no tomorrow. In response to the MIT Climate Portal, methane fuel “traps round 100 occasions 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 train at Victoria College of Wellington, revealed a e-book through which they crunch the numbers relating to the damaging environmental affect of pet possession — Time to Eat the Canine: The Actual Information to Sustainable Residing. Their conclusions have been surprising.
The common 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 varied grains, the Vales calculated it requires roughly .84 hectares of land to feed a canine the scale 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 less food 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 revealed in PLOS One reached related conclusions whereas describing the phenomena a bit in a different way. After tapping the American Kennel Affiliation for details about the ten hottest canine breeds, Gregory Orkin, writer of this progressive 2019 examine, averaged their weights. In response to Orkin’s calculations, the common canine in the USA weighs 22 kilos, greater than the common cat who suggestions the scales at 10 pounds. Canines 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.
On account of weight variations, the environmental affect of feeding the common pet cat is decrease than that concerned in holding a mean canine correctly fed. When weight and inhabitants numbers are factored collectively, US canine devour excess of US cats.
Companion animal possession has critical environmental penalties—cats and canine collectively eat round 24% of all the animal-based energy consumed within the US or about one-third of the meat eaten within the nation. These numbers might sound exaggerated till you understand that round 70% of US households have not less than one pet—there’re round 69 million homes with pet canine and 45.3 million properties with cats.
The US has the most important companion animal inhabitants on the planet. And we might feed round 62 million people with the meals and power that goes into meals manufacturing for US pets.
And issues will most likely worsen as worldwide tendencies in pet ownership proceed. Whereas companion pets have been widespread in North America, Europe, and Australia for many years, the observe is turning into more and more widespread in creating and middle-income nations. Because the variety of companion animals stored in properties around the globe will increase, so too will the magnitude of those animals’ environmental affect.
There additionally seems to be a shift in values underway, altering the best way many consider cats and canine. In response to 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 canine.
What About Poop and Kitty Litter?
Our animal companions aren’t doing us any favors within the poop division, both. The average 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 canine. Cats are likely to weigh a lot lower than canine and subsequently produce much less waste on common.
Canines and cats collectively are liable for about 23% of all poop excreted within the US—people are liable for the remaining. Companion canine and cats produce as a lot waste because the human inhabitants of a state across the measurement of Massachusetts, most of which results in landfills the place it decomposes, releasing methane — a major contributor to international warming—into the environment.
After which you’ve gotten the environmental affect of all that kitty litter. Sadly, most research evaluating the environmental affect of pet possession solely take into account the implications of feeding companion animals, failing to account for elements equivalent to the prices of manufacturing and disposing of kitty litter, that are fairly substantial when you think about the harms brought on by 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 international warming every time they alter their cat’s litter.
There are a number of methods to get began if you happen to’re critical about lowering your cat’s environmental affect. One is tremendous easy—the others require a bit extra dedication and planning. The quickest and best technique to scale back your cat’s environmental affect 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 an incredible selection when you have the curiosity, the cash and your cat tolerates the change. There are tons of biodegradable choices available on the market made out of sustainable merchandise equivalent to recycled newspapers, dried tofu and wooden chips. There are clumping and non-clumping varieties in addition to fragranced and unscented selections. You’ll be able to even compost un-peed or pooped on components 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 critical about minimizing your cat’s environmental footprint, take into account 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, equivalent to Open Farm, that adhere to robust sustainability and transparency requirements and others, equivalent to The Honest Kitchen, that function as B companies pledged to issue parts equivalent 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 link to an article with a number of tips about the best way to discover a respected carbon offset program that aligns together with your values).
Conclusion
Cats are typically higher for the setting than canine in the case of the largest offender — meals manufacturing. As a result of cats are smaller than most canine and subsequently usually devour much less meals and produce much less poop, cats have much less of a damaging affect on the setting than canine. That’s nice information if you happen to 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 unattainable to say cat possession is something near earth-friendly. Utilizing biodegradable kitty litter, buying cat meals and treats from corporations that function based on sound sustainability ideas and investing within the occasional carbon offset can go a good distance in the direction of lowering the damaging affect cat possession has on the setting.
