I Tried the Greatest At-House Pet DNA Check Kits on My Two Cats (2025)

If You Have a Canine, Take into account These Kits

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

How Does a DNA Testing Package Work?

Pet DNA assessments depend on pet house owners accumulating cells for testing by means 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 one more package to be despatched, re-swab him, and wait one other 5 weeks for outcomes.)

On the lab, the pattern is analyzed towards the corporate’s breed and genetic well being database. They use single nucleotide polymorphism (SNP) arrays—the usual expertise used to determine breed ancestry—in addition to varied inherited traits and threat of widespread illnesses. Primarily, 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 examine them to the corporate’s present database to estimate the composition of breed varieties within the animal. This not solely tells you about breed composition, however can even determine the particular DNA sequences which are 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, nonetheless. “This may 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 service for any genetic illness.

Limitations of At-House DNA Check Kits

After chatting with Jamie Richardson, head of veterinary drugs 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 rely on the dimensions/variety of the genetic database
• Most kits take a look at identified markers solely—not full genomes
• Feline knowledge 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 canine are over 99 p.c correct.

I’ve outlined the outcomes beneath, so you may see the disparity in outcomes from the 2 kits I examined, significantly with breed ancestry.

One downside with the huge disparity in outcomes is that the 2 corporations have completely different pattern sizes and metrics for figuring out breeds. However the largest subject for cat house owners taking these at-home DNA assessments is that you would be able to’t actually determine most cats’ breeds the best way you may with canine. 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 essentially the most markers with. Principally, these assessments for cats aren’t in a position to reliably inform us about breed composition, simply similarity to different breeds’ traits within the firm’s knowledge pool.

From my analysis, it appears the breed identification a part of these assessments is extra correct for canine, 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 only a few generations. Cats should not a lot completely different from their Egyptian ancestors.

Curiously, in 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 bought varied 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 method to decide a pet’s genetic make-up or ancestry. People like classes. And breeds are basically human constructs, based mostly on the best way 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 realize that there’s a major disparity in outcomes based mostly on the pool the pattern is in contrast towards.

For instance, beneath are the outcomes I bought 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 completely “American home cat” and “polycat/home shorthair”—mainly the mutt ultimate boss, a results of many generations of combined breeding between several types of cats, the place ancestry and origin is nearly unattainable to find out.)

Well being Outcomes

Knowledge Panel assessments for 49 genetic well being predispositions by evaluating the pet’s DNA towards a panel of cat or canine genetic well being checks. It assessments for the highest 5 genetic circumstances that might impression the pet’s vet visits—basically, the most typical circumstances which are seen in cats or canine with an analogous 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 kind (each of my cats had been A) and transfusion threat (each had been reasonable).

Basepaws assessments for as much as 115 well being markers, however my cat obtained outcomes for under 44 genetic illnesses (house owners are inspired to verify outcomes typically in case lacking markers are added as extra knowledge turns into obtainable). This checklist felt extra in-depth than the Knowledge Panel take a look at, testing genes for markers towards issues in musculoskeletal and connective tissue; eyes; metabolic, autoimmune, and endocrine programs; 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 kind and transfusion threat, which had been A and reasonable (the identical outcomes I bought 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 greater threat of it. I might encourage house owners to succeed in 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 downside in lots of pets, and may 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 towards an oral microbiome database. On this regard, Basepaws wins out.

In keeping with 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 may very well be indicative of a bigger well being subject, however she was cleared for illness, so I wasn’t positive what to do with that info.

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 day by day oral healthcare routine, contemplate 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 useful subsequent steps so I may give you a plan of motion for care. And it’s vital to do not forget that these outcomes don’t essentially imply a pet is assured to develop the illness.

“These generally is a useful flag on your veterinarian to keep watch over […] however doesn’t essentially imply aggressive testing is required at that second,” says Richardson. “DNA assessments are instruments to assist—not change—veterinary care.”

Traits Outcomes

Each of the assessments had this part, which assessments for coat coloration traits and variants, however I discovered it largely ineffective. Knowledge Panel’s assertions of each cats’ bodily traits had been right. However with Basepaws, Clover, a dilute calico, was marked as being possible black in coloration.

I can see with my eyes what my cat(s) appear like, however if you happen to’re a genetic nerd, this is perhaps enjoyable to see what the precise DNA displays.

A Word on At-House Allergy Testing Kits

I just lately examined each of my cats for his or her allergy symptoms and intolerances utilizing an analogous at-home take a look at package, 5Strands Pet Meals & Environmental Intolerance Check for $100. For this, you solely have to 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 widespread substances of their eating regimen, like varied varieties of fish and hen 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 are not an correct method to measure allergy symptoms and intolerances, and research present kits claiming to offer these outcomes carry out no higher than likelihood and infrequently produce inconsistent or false outcomes.

“There is not any scientific proof to assist allergy testing by means 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 normal.”

So, save your cash and seek the advice of a vet as a substitute if you happen to suspect your pet is struggling due to allergy symptoms or intolerances.
