If You Have a Canine, Contemplate These Kits
I don’t have a canine, so I did not attempt these at-home DNA take a look at kits for canines, however these are the kits particularly for canines from Basepaws and Knowledge Panel, the 2 corporations I’ve examined for my cats.

How Does a DNA Testing Equipment Work?
Pet DNA assessments depend on pet homeowners accumulating cells for testing by way of a cheek swab, the place the pattern is put right into a sealed stabilizing or preserving fluid for transit. You’ll mail the pattern again to the lab within the pay as you go envelope. It takes as much as 5 weeks to get outcomes. (The primary time I despatched my cat Basil’s Basepaws pattern, the corporate emailed that the outcomes had been inconclusive, and I needed to wait for an additional package to be despatched, re-swab him, and wait one other 5 weeks for outcomes.)
On the lab, the pattern is analyzed in opposition to the corporate’s breed and genetic well being database. They use single nucleotide polymorphism (SNP) arrays—the usual know-how used to determine breed ancestry—in addition to numerous inherited traits and threat of frequent illnesses. Basically, completely different breeds have distinct patterns of SNPs of their genomes, which act because the genetic markers. These assessments analyze the pet’s DNA pattern for particular SNPs after which evaluate them to the corporate’s current database to estimate the composition of breed sorts within the animal. This not solely tells you about breed composition, however may also determine the particular DNA sequences which can be markers for potential well being dangers, like predispositions to illnesses or hereditary cancers.
Don’t take the well being or DNA take a look at outcomes as absolute reality, nevertheless. “This will result in a false sense of safety or false alarms,” says veterinarian Amanda Chambers. Ahead your outcomes to your veterinarian and at all times comply with up with scheduling a go to to the vet in case your pet is marked as a provider for any genetic illness.
Limitations of At-House DNA Check Kits
After chatting with Jamie Richardson, head of veterinary medication at Small Door Veterinary, I’ve discovered that these are the key areas of limitations with at-home DNA take a look at kits:
- Outcomes depend upon the scale/range of the genetic database
- Most kits take a look at recognized markers solely—not full genomes
- Feline information is much less developed
- Misinterpretation of outcomes can result in pointless concern
How Correct Is At-House DNA Testing?
Knowledge Panel claims its breed outcomes for cats are over 98 p.c correct and that assessments for canines are over 99 p.c correct.
I’ve outlined the outcomes under, so you’ll be able to see the disparity in outcomes from the 2 kits I examined, notably with breed ancestry.
One drawback with the huge disparity in outcomes is that the 2 corporations have completely different pattern sizes and metrics for figuring out breeds. However the greatest challenge for cat homeowners taking these at-home DNA assessments is you can’t actually determine most cats’ breeds the way in which you’ll be able to with canines. Until your cat is a purebred, round 95 p.c of cats don’t belong to a acknowledged breed. Cats’ genetic backgrounds are muddied—they’re simply comparable mixes with completely different bodily traits, so the assessments solely present the breed(s) they share probably the most markers with. Principally, these assessments for cats aren’t capable of reliably inform us about breed composition, simply similarity to different breeds’ traits within the firm’s information pool.
From my analysis, it appears the breed identification a part of these assessments is extra correct for canines, as canine DNA is a lot extra diversified. Breeds have been clearly outlined after centuries of diversifying from different breeds, and canine DNA mutates rapidly, with genes altering rapidly after just some generations. Cats usually are not a lot completely different from their Egyptian ancestors.
Curiously, on this report from CBS in 2023, the information group despatched canine and human DNA to completely different at-home take a look at corporations and received numerous outcomes, starting from 65 to solely 29 p.c German shepherd DNA for the canine. The human DNA outcomes had been attributed to a bulldog, border collie, and cane corso combine.
TL;DR
There is not one catch-all approach to decide a pet’s genetic make-up or ancestry. People like classes. And breeds are primarily human constructs, based mostly on the way in which the canine or cat appears to be like. The genetic a part of the take a look at is enjoyable, however take it with a grain of salt—particularly with cats.
Ancestry Outcomes
Should you learn above, you already know that there’s a major disparity in outcomes based mostly on the pool the pattern is in contrast in opposition to.
For instance, under are the outcomes I received for my cat Clover, who’s a dilute calico with lengthy, white fur and visually appears to be like most like a Maine coon or Norwegian forest cat.
(I additionally examined my run-of-the-mill grey cat Basil, however he was virtually fully “American home cat” and “polycat/home shorthair”—principally the mutt last boss, a results of many generations of combined breeding between various kinds of cats, the place ancestry and origin is sort of inconceivable to find out.)
Well being Outcomes
Knowledge Panel assessments for 49 genetic well being predispositions by evaluating the pet’s DNA in opposition to a panel of cat or canine genetic well being checks. It assessments for the highest 5 genetic circumstances that might influence the pet’s vet visits—primarily, the commonest circumstances which can be seen in cats or canines with the same breed make-up as your pet. These are for issues like drug sensitivity, immune deficiency, and bleeding issues. In addition they recognized the cat’s blood sort (each of my cats had been A) and transfusion threat (each had been average).
Basepaws assessments for as much as 115 well being markers, however my cat acquired outcomes for less than 44 genetic illnesses (homeowners are inspired to test outcomes typically in case lacking markers are added as extra information turns into obtainable). This checklist felt extra in-depth than the Knowledge Panel take a look at, testing genes for markers in opposition to issues in musculoskeletal and connective tissue; eyes; metabolic, autoimmune, and endocrine methods; blood; and extra. Each of my cats, Clover and Basil, had been cleared as having not one of the genes that mark them as potential carriers of genetic illnesses. It additionally recognized blood sort and transfusion threat, which had been A and average (the identical outcomes I received with Knowledge Panel’s take a look at).
In case your pet will get flagged for any of those outcomes, don’t panic. “The presence of a sure gene doesn’t at all times imply a affected person will develop a sure dysfunction that’s related to that gene—it simply means they’re at increased threat of it. I’d encourage homeowners to achieve out to their veterinarian if they’ve questions after receiving the outcomes of a DNA take a look at,” says Chambers.
Oral Well being Outcomes
Knowledge Panel doesn’t display for oral well being, which is a big drawback in lots of pets, and might result in tooth extraction and greater well being points.
Oral well being was a priority for me, and Basepaws assessments for oral well being by testing in opposition to an oral microbiome database. On this regard, Basepaws wins out.
In response to the Basepaws outcomes, Clover was a low threat for periodontal illness and tooth resorption, however at a excessive threat of halitosis. The report stated unhealthy breath could possibly be indicative of a bigger well being challenge, however she was cleared for illness, so I wasn’t certain what to do with that data.

My different cat, Basil, was at excessive threat for all of the dental markers talked about above, and Basepaws got here up with a well being plan for him: “undertake a every day oral healthcare routine, think about supplementing Basil’s routine with merchandise accepted by the Veterinary Oral Well being Council, and schedule an appointment together with your veterinarian within the subsequent month.”

Though I used to be alarmed on the outcomes, I preferred that Basepaws gave me really helpful subsequent steps so I might give you a plan of motion for care. And it’s essential to do not forget that these outcomes don’t essentially imply a pet is assured to develop the illness.
“These could be a useful flag in your veterinarian to control […] however doesn’t essentially imply aggressive testing is required at that second,” says Richardson. “DNA assessments are instruments to assist—not substitute—veterinary care.”
Traits Outcomes
Each of the assessments had this part, which assessments for coat shade traits and variants, however I discovered it largely ineffective. Knowledge Panel’s assertions of each cats’ bodily traits had been appropriate. However with Basepaws, Clover, a dilute calico, was marked as being seemingly black in shade.
I can see with my eyes what my cat(s) seem like, however should you’re a genetic nerd, this could be enjoyable to see what the precise DNA displays.
A Observe on At-House Allergy Testing Kits
I lately examined each of my cats for his or her allergy symptoms and intolerances utilizing the same at-home take a look at package, 5Strands Pet Meals & Environmental Intolerance Check for $100. For this, you solely must ship a fur pattern within the mail to a lab; outcomes had been despatched to my inbox inside seven days. The report confirmed that each of my cats confirmed robust intolerances to frequent elements of their weight loss program, like numerous sorts of fish and rooster meal. This despatched me right into a panic concerning the well being and (dis)consolation of my cats.
After extra analysis, I discovered that hair/fur samples usually are not an correct approach to measure allergy symptoms and intolerances, and research present kits claiming to offer these outcomes carry out no higher than probability and sometimes produce inconsistent or false outcomes.
“There is no scientific proof to assist allergy testing by way of hair, fur, or saliva,” says Richardson. “Veterinarian-supervised elimination diets to check for meals allergy and intra-dermal pores and skin testing or blood assessments to check for environmental allergy symptoms stay the gold commonplace.”
So, save your cash and seek the advice of a vet as a substitute should you suspect your pet is struggling due to allergy symptoms or intolerances.
