Based on the approach she appears and acts, everybody assumes that Tinkerbell, our bobtailed dilute calico, is a Japanese Bobtail. And it can be a stretch, however we expect our extremely affectionate, domineering black cat, Toby, could be section Bombay. Are we on the mark, or is that this simply wishful serious about the genetics of our two wonderful and adored kitties? We grew to become to a cat DNA take a look at to determine.
We ordered cat DNA take a look at kits from the two main puppy DNA research corporations, Basepaws and Wisdom Panel. After registering our cats on the corporations’ web sites, we accumulated DNA samples at house (a procedure described intimately, beneath) and mailed them in for research. Then we settled again to look forward to the thrilling revelations about Toby and Tinkerbell’s ancestries, characteristics, and gene-linked well being dangers.
During the wait, we studied the data on cat DNA exams ready for Rover in 2019 by means of Emilie Bess, a DNA scientist with some extent in molecular evolution. Bess wrote the authentic model of this newsletter that we’re now updating with exact take a look at research from my two cats.

A Quick Explanation of Breeds and Genetics
Bess’ explanations did so much to mood our expectancies about what a cat DNA take a look at may just—and couldn’t—let us know about Tinkerbell and Toby. It seems that DNA trying out unearths some distance much less about cat breeds than it does about canine breeds. (Find out about canine DNA exams right here.) This is on account of the other ways in which cats and canine have been domesticated.
“Dogs have been the first animals to be domesticated by means of people, someplace between 14,000-40,000 years in the past. Cat began putting round with humans best about eight,000 years in the past, and their domestication procedure used to be a lot more sluggish,” says Bess.
“We actively domesticated dogs,” Bess continues. “Cats…not so much. Dogs were selected for their ability to perform specific tasks, such as guarding, shepherding, and companionship. Selective breeding for the physical and personality traits led to the development of dog breeds, which began very early in the relationship between humans and dogs, more than 10,000 years ago.”
This implies that canine breeds are genetically distinct. In DNA phrases, a Chihuahua and a Golden Lab are very other from one every other. (For additional information, listed here are some contemporary research on the genetics of canine breeds.)

While canine have been being intentionally bred for specific characteristics, cats just about domesticated themselves. There is proof that breeding for tabby markings started in the 18th century, however the construction of distinct cat breeds that experience particular bodily and character characteristics didn’t get critically underway till about 150 years in the past when breeds like Abyssinian, Persian, and Maine Coon have been advanced (nowadays there are 45 cat breeds known by means of the Cat Fanciers Association).
Some uncommon breeds had been round for lower than 50 years. That’s no longer lengthy sufficient for genetically tough variations to exist.
This implies that even two cats that glance as other as a Silver Tabby and a Norwegian Forest cat are genetically lovely identical.
“90% of home cats don’t have any purebred bloodline in any respect,” they appear and act simply as their historical ancestors did, and they percentage just about an identical genetics,” Bess says.

Interpreting Cat DNA Test Results
While a cat DNA take a look at would possibly not inform you a lot about your cat’s breed, you will to find out somewhat a bit of about the place your cat’s ancestors got here from.
Modern home cats originated from Egyptian cats (very similar to nowadays’s Egyptian Mau) and unfold during Europe, Asia, Africa, and the Americas. Genetic markers have proven that cats are differentiated into distinct teams in those 4 areas: the Mediterranean basin, Europe/America, Asia, and Africa. Cat DNA take a look at effects will inform you which of those teams your cat is descended from.
Some cat DNA exams supply effects that point out in case your cat has a “marker” for a undeniable well being possibility. Of this, Bess is skeptical. She says to not concern if a take a look at says your cat has a marker for a selected illness. It does no longer imply your cat has the illness, or that your cat goes to get the illness.
Researchers writing in the magazine Nature indicate that “most of these [pet DNA] tests are based on small, underpowered studies. Neither their accuracy nor their ability to predict health outcomes has been validated. Most vets don’t know enough about the limitations of the studies, or about genetics in general, to be able to advise worried owners.”
So, whilst you’re most likely to be informed extra about your cat’s genes than you presently know, the data you obtain is not likely to be conclusive.
How Cat DNA Test Kits Work
DNA kits assist you to acquire a pattern of your cat’s saliva or cheek cells to be mailed to the corporate for research. Depending in your cat’s character, this is a breeze…or a bit of of an journey. We took samples from every cat with exams from two corporations, Basepaws and Wisdom Panel.
Both kits arrived in the mail with the instructions and apparatus you want to assemble the samples. Note: Be positive to avoid wasting the ones packing containers, since you’ll be the usage of them to send the samples again.
Once you open the field, pass to the corporate’s site to sign in your cat and the numbered take a look at package. Now you’re in a position to take the exact pattern out of your cat.
Collecting DNA Samples From Your Cat
Basepaws field, with swab
The Basepaws field comes with directions published on the field itself. They have been easy and smooth to observe.
The field contained a swab, just like a large strong Q-tip, and a tiny plastic take a look at tube stuffed with a liquid for delivery the swab together with your cat’s saliva pattern. You insert the swab into your cat’s mouth, in the cheek pouch, for 5 seconds. Then insert the swab into the take a look at tube, shut the take a look at tube, and send it again to Basepaws.
Both Tink and Toby submitted to being swabbed with best minor annoyance. So, a “paws up” throughout! We shipped the kits and sat again to look forward to our effects.
Toby will get examined with a Basepaws swab
Wisdom Panel package
The Wisdom Panel field additionally comes with easy-to-read, step by step, directions. We visited the site to sign in the cats and the kits. Then, issues were given sophisticated.
Instead of swabbing inside of the mouth for five seconds for saliva (as we did for Basepaws), you swab the within the cat’s cheek pouch for 15 seconds with a tiny plastic comb designed to assemble cells. (This is referred to as a buccal swab.) Then you swab the within the cat’s cheek pouch for every other 15 seconds, with a moment comb.
You let the combs dry for five mins (in a pitcher or different container that you just supply). The dry samples pass into the incorporated pattern envelope that you just send in the field again to Wisdom Panel.
On one hand, it sort of feels most likely that the cheek cells supply a in reality tough DNA pattern, much less more likely to be infected by means of cat meals than the saliva we despatched to Basepaws. On the different hand, it used to be tricky to get Tinkerbell to position up with 15 seconds of cheek swabbing, and even extra tough to get her to put up to a moment spherical of cheek swabbing. The Wisdom Panel sampling is without a doubt a two-person operation! Tom held Tinkerbell whilst she struggled violently and I swabbed.
I swear that Toby didn’t witness any of Tink’s studies. Nevertheless, he refused to allow us to habits even the first spherical of cheek swabbing for the Wisdom Panel. Despite being 24 years previous, Toby has all of his tooth, and he made it transparent that he used to be in a position to make use of them. So we known as our veterinarian and made an appointment to have a technician acquire Toby’s samples.
Tip: If you make a decision to make use of Wisdom Panel (which we appreciated somewhat a bit of) it is going to make sense to look forward to your cat’s annual checkup and ask your vet’s staff to assemble the DNA samples. Our vet techs appeared very conversant in the process.
Wait Time
Basepaws tell us when our samples have been gained, once they have been being analyzed, and when the take a look at effects have been in a position to view on their web page (about 4 weeks when we’d mailed in the samples). Wisdom Panel tell us when the samples have been gained and when the effects have been in a position to view (about two weeks when we’d mailed in the samples).
Tinkerbell. Is she a Japanese Bobtail?
What We Found Out About Our Cats’ DNA and Health
Keep in thoughts that the DNA exams we bought glance best at genes related to cat breed, some bodily characteristics, and increased possibility of a few quite uncommon well being stipulations. (You can purchase a costlier take a look at from Basepaws that does extra in depth genome sequencing.)
That mentioned, we discovered our cats’ effects to be attention-grabbing. And there have been indubitably some variations in the approach the two corporations introduced our cats’ information.
Tinkerbell’s Results
Let’s get started by means of taking a look at Tinkerbell’s effects. With dilute calico markings and a bobtail, used to be she a Japanese Bobtail?
Answer from each Basepaws and Wisdom Panel: Unlikely.
Wisdom Panel breed research
Basepaws breed analyses (conceivable vs. assured)
While Tinkerbell isn’t a Japanese Bobtail, a few of her ancestors could have been, for the reason that a few of her geographic ancestries is Asian (often known as Eastern or Siamese/Oriental).
While Basepaws didn’t have anything else to mention about Tinkerbell’s bobtail, Wisdom Panel did.
The Wisdom Panel characteristics information additionally showed that her adorable little quick tail is a genetic trait. However, once we did a deeper dive into the effects, we will be able to see that her quick tail genes are regularly related to Manx fairly than Japanese Bobtail cats. OK, Tinkerbell: You’re from the Manx circle of relatives.
Wisdom panel characteristics research (bobtail)
While we were given extra information from Wisdom Panel, we in reality appreciated the approach that Basepaws displayed the breed research data. You can make a choice the degree of simple task you need to view, starting from “maybe” and “possible” to “likely” and “confident” (see our screenshot, above, for the variations in Tinkerbell’s effects).
Toby. Is he a Bombay?
Toby’s Results
Let’s check out Toby’s effects. Is our super-friendly pal with a brief black coat and giant gold eyes associated with Bombays?
Answer from Basepaws and Wisdom Panel: Unlikely.
Wisdom Panel breeds research
Basepaws breed research
Yes, Toby is your elementary Western cat (in keeping with Wisdom Panel) or your elementary Western and “polycat” (in keeping with Basepaws). But—wait a minute! What on earth is a “LaPerm?” Wisdom Panel’s Breed Explorer Feature allow us to learn about this interesting breed of small, people-oriented, curly-haired cats that originated in Oregon in 1982. While Toby isn’t a LaPerm, he does percentage some ancestors with them.
Wisdom Panel well being effects
Both Wisdom Panel and Basepaws checked out our cats’ DNA to peer if our cats are genetically disposed to a better possibility of positive well being stipulations for which they’ve comparative information. The resolution, for each cats, used to be no increased dangers. So I will’t say a lot about that a part of the DNA trying out.
So, Should You Try a Cat DNA Test?
Bess concludes, “At this point, cat DNA tests are marketed as a novelty and intended to satisfy curiosity about the origins of our pets. You’ll get some cool info about where on earth your cat’s ancestors lived, and you might even get some information on your cat’s health. You’ll be joining a growing community of cat lovers who are contributing to the understanding of cat genetics. Depending on what service you use, you might get future updates that give you more information as their database expands and improves.”
For our section if truth be told trying out those kits on my cats, we have been happy with each exams.
We appreciated Wisdom Panel’s detailed exam of gene-linked characteristics, comparable to Tinkerbell’s bobtail. But we most well-liked Basepaws’ smooth, Five-second saliva take a look at to Wisdom’s Panel’s extra advanced, two-swab assortment strategies.
Two different Cat DNA exams are to be had that we didn’t take a look at. They are:
- Neogen’s Cat DNA take a look at, designed for breeders and humans concerned about parentage and well being data for purebred cats
- Orivet Cat DNA Test Kit, that specialize in well being problems fairly than breed data (if truth be told, it calls for you “know the breeds that make up your cat” earlier than you order the take a look at)
We need to admit, we loved seeing the result of the Wisdom Panel and Basepaws. So a lot so, that we’ve ordered every other take a look at for Max, the community cat we followed.
Is Max actually a Siberian with a triple-layer coat?
We don’t assume he cares.
Max. Could he be a Siberian?
