Please Keep Your Cats Indoors

Invasive Species

While cute, this cat is a killer.

Cats are wonderful. They are soft, cuddly, and are a sensation on YouTube. Being carnivores, cats are also well adapted predators. There are millions upon millions of cats around the world. Some are pets, some are strays, and some are feral. Fact: The domestic house cat is an invasive species. An invasive species is defined as an organism (plant, animal, fungus, or bacterium) that is not native and has negative effects on the environment. Invasive plants and animals are the second greatest threat to biodiversity after habitat loss.

How much do cats really kill? According to research published in the journal Nature Communications, every year cats kill between 1.4 billion and 3.7 billion birds and between 6.9 billion and 20.7 billion small mammals. These numbers are staggering and without a doubt cats pose a threat to native wildlife. Need more data to back up this claim? Check out this educational, albeit hilarious, info-graphic by the Oatmeal: http://theoatmeal.com/comics/cats_actually_kill

NOTE: Globally wildlife populations are declining at an alarming rate. Besides invasive species, wildlife are threatened by habitat destruction, infectious diseases, climate change, over-harvesting, and more! This article is not anti-cat, but rather it is to bring awareness to the impact cats have on native wildlife.

Mouse Opposum

Back story: I am currently managing a 200 acre field station in the heart of the Maya Mountains of Belize. I have many responsibilities as station manager, but one of them is to make sure the pets are properly looked after. There are two cats that live on the property and one of them is an excellent hunter. Late last night I discovered that this feline had procured a small, adorable mammal.

Whenever I find that the cat has caught something, I try to take it away as soon as possible. The captured creature might still be alive and these cats are well fed and definitely do not need to be killing animals for their food! However, in most cases the animal has quickly been killed by the cat. Tonight I could see that this little mammal was struggling so I got it from the cat! Right away I knew what it was, a beautiful Mexican Mouse Opossum, Marmosa mexicana.

The opossum was in shock, and for good reason, it nearly lost its life! After a few minutes it started to calm down. I was preparing to keep it over night, and in the morning I would assess its wounds. Yet, after ten minutes it seemed as if the little one was ready to be released.

It seemed to say, “Let me out! Let me out! Let me out!”

It appeared to have minor woulds so I released it back out into the forest. I watched it scale a tree with little effort and hopefully it will survive. So, use this opossum’s situation as a reminder: Be a responsible pet owner, a friend to native wildlife, and keep your cats indoors!

  1. I agree, humans domesticated cats so we need to take responsibility for their actions. And that is such an adorable mouse! I hope he/she has a happy full life. It’s so nice to see others who care about native wildlife. Thanks for posting!

  2. You may think you saved that small animal’s life from a cat-attack, but it is more than 99% certain that that small animal went on to die a slow and painful death from bacterial infections from the puncture wounds of any cat. People love to claim how they let a bird go free after their cat caught it, but that bird will die days or weeks later in torment being eaten from the inside-out by deadly bacteria. If you want to poison all your native wildlife to death by using bio-warfare, you need do nothing more than let cats roam free.

    And birds are just a minor subset of all the thousands of native animal species (billions of individual animals) that cat-lickers (criminally irresponsible cat-advocates) are annihilating around the world with their man-made invasive species vermin cats.

    Not only are these demented invasive-species house-cats-ONLY “animal lovers” now killing off all Big Cats in all wildlife reserves around the world:

    And for the ultimate example of absurdity and species-conservation irony, now making all moggie-licking residents of the UK (the inventors of that TNR insanity) the complete laughingstocks of the whole world, they’ve already made their ONE AND ONLY NATIVE CAT SPECIES EXTINCT in the UK with their invasive species “moggies”:

    http://www.guardian.co.uk/environment/2012/sep/16/scottish-wildcat-extinction

    “A report, produced by the Scottish Wildcat Association, reviewed 2,000 records of camera trap recordings, eyewitness reports and road kills, and concluded there may be only about 40 wildcats left in Scotland in the wild today. ‘However you juggle the figures, it is hard to find anything positive,’ says Steve Piper, the association’s chairman. ‘The overwhelming evidence is that the wildcat is going to be extinct within months.'” … “However, it is not the loss of habitat that is causing the current cat crisis in the Cairngorms. It is the spread of the domestic cat.” … “‘Essentially the Highland wildcat is being eradicated by an alien invasive species: the domestic cat.'” (report quoted from 2 years ago, they are no-doubt extinct by now)

    As well as killing off all their inland River Otters in England (and elsewhere) with their cats’ parasites:

    As well as cats’ parasites killing off all rare and endangered marine mammals on all coastlines around the world (worse than any oil-spill that has ever existed or could even be imagined):

    Plus these cat-licking “animal lover” psychopaths and sociopaths are also killing off all the Mountain Lions (Cougars, Puma, Endangered Florida Panther, etc.), and all other native cat species in North America:

    But now these cat-lickers are even killing off rare whales and causing massive birth-defects in the indigenous Inuit people who depend on seal-meat for their very survival. Seals that were infected (and are also dying-off) from these cat-lickers’ cats’ parasites.

    Let’s thank these psychotic bible-home-schooled cat-lickers for all the fine work they do for being such fantastic “animal lovers”, shall we? THEY JUST LOVE CATS SO MUCH! So caring! So thoughtful! So intelligent! So FULL of love for living things! So much so that they will even sacrifice whole races of humans to death-by-birth-defect to prove how much they love their cats.

    I’d love to thank them all, each with a gift of a solitary-confinement prison-cell — FOR LIFE. Better yet, for their VAST ecological crimes and sins against all of nature and all of humanity, hanged-until-dead would be a far more fitting “gift” for them AND the whole planet. That used to be the punishment for engaging in bio-warfare against the human population and all other animal life in any country. I say bring it back — special, just for them.

    1. Quite the reply and thank you for your comments. I appreciate the fact that you linked your claims with articles and sources. I have heard about the transmission of toxoplasmosis along the Pacific Coast that has greatly impacted sea otters, but I was not aware this is an issue for other species (although it makes sense that it would).
