Is It Safe for Your Cat to Eat Bugs?
You don’t have to be a cat or dog aficionado to know just how different these two species are—the signs are all around us. While dogs are considered “man’s best friend” and have been domesticated, the social contract between cats and people has a few grey areas. It’s as if cats considered our offer of being fed and having a warm place to sleep and answered, “OK, we’ll take care of the rodents, but as for the rest of that stuff—you’re on your own.”
While we might view photographs and artwork containing dogs as the picture of domesticity, images of felines often seem to portray a wild predator lurking just beneath the surface. In our modern world, we’ve indeed taken the cat out of the jungle (or desert, to be precise), but we haven’t been as successful in taking the jungle out of our cats. Whether your cat is always crouched in a corner waiting to attack your feet as you walk by or bringing the spoils of an outdoor hunt to your welcome mats and carpets (or to your bed!), even the cutest moggy is a little wild-at-heart.
Cats love to hunt. They love to stalk, chase, and catch. And having a constantly filled food dish doesn’t seem to quell this desire one bit. For cats living indoors, where wild game is scarce, many will go for the next best thing: insects.
WHY DO CATS CHASE BUGS?
Chasing bugs is a lot more fun than a feather tied to a stick or a ball with a bell inside. Such cat toys don’t speak to the “inner panther” in your cat the way that a living creature desperate to preserve its life does, so it’s not surprising that cats just plain love hunting insects. But is this practice harmful to a cat’s health?
The term obligate carnivore, or true carnivore, is defined as an animal that must eat animal sources of protein to survive. Other mammals that are obligate carnivores exist on both the land and in the sea, and include minks, dolphins, seals, sea lions, and walruses. Non-mammal obligate carnivores include rainbow trout, salmon, hawks, eagles, crocodilians, and many snakes and amphibians.
INTERNAL PARASITES IN BUGS
“Internal parasites are not a [big] concern with ingestion of insects,” says Dr. Katie Grzyb, DVM. “The danger from ingesting insects is very small.”
Some types of insects can carry parasites that are able to infect cats, like Physaloptera, or stomach worm, but these cases are few and far between.
Bugs may also have an irritant effect on the gastrointestinal tract of cats. Vomiting and/or diarrhoea is the common result. If it is severe or doesn’t resolve on its own in a day or two, make an appointment with your veterinarian.
But Dr. Coates says that some types of insects certainly can become a problem when they infest or live on the coat of a feline. “Fleas can carry tapeworms or make cats anaemic, and ticks, while technically not insects, can transmit several diseases to animals and people. In other words, there may be more to worry about when it is the bug that is doing the biting.” Dr. Grzyb adds “bee stings and spider bites certainly can cause an allergic reaction, localised or anaphylactic, which often needs to be treated by a veterinarian.”
DO PESTICIDES MAKE BUGS POISON TO CATS?
We do our best to keep insects out of the house, and many of us turn to insecticides to combat bugs when they venture inside. Since these poisons can be found on and inside the bodies of insects while they are still alive and kicking, pet owners might be concerned about the effect that eating a poisoned insect could have on their pets. As it turns out, in most cases there isn’t any need to worry.
“The dying bugs have such a low amount of toxin that it is very unlikely that an owner will see any side effects in their pet.” says Dr. Grzyb.
The situation can be very different when a cat comes in direct contact with an insecticide, however. When pet owners are going to use any type of chemicals around the home, insecticides or otherwise, a little research is always your best bet. In other words, read the label.
“When using insecticides it is pertinent to make sure that the owner reads the label to make certain there are no pyrethroids as these can cause severe tremors, elevated temperature, and seizures in some felines,” says Dr. Grzyb.
On the other hand, “I have seen many cases of roach bait ingestion, which almost never causes any side effects in cats; possibly mild gastrointestinal signs, but that’s all.”
“If an owner thinks that their animal has ingested an insecticide, I recommend contacting their local veterinarian or a Poison Control Hotline, such as the ASPCA,” says Dr. Grzyb. “It is helpful for the owners to have as much information about the product when contacting these sources, such as the bottle in hand to read off active ingredients.”
DO CATS MISS HUNTING?
Do our cats miss the daily hunt for game, and bugs just happen to serve as a handy replacement for this instinct? Or is it just kittenish behaviour that persists over the life our cats?
“Yes, I do believe that cats use insects as a substitute for hunting. Kittens in general are more playful so they may seem to ‘hunt’ more often, but it is really just play time,” says Dr. Grzyb.
“If you watch cats, they oftentimes won't even ingest the insect; they will hunt, bat, and place them in their teeth, but oftentimes will not swallow it. So, though we will likely never know for sure, domesticated cats seem to be hunting to pass the time.”
So, while your cat’s bug-hunting might be bad news for the insects in your home, it all comes down to cats being cats—staying wild-at-heart and having fun while they’re at it.
