Introduction
Some relatively new commercial DNA tests for cats allow owners to determine their cat’s breed makeup and ancestry. Similar to canine DNA tests, cat DNA tests analyze genetic markers from a cat’s cheek swab or hair sample to identify breeds in its family tree and genetic traits [1]. Some advanced DNA tests like Basepaws and Wisdom Panel can even locate genetic relatives such as siblings, parents, and grandparents, if they have also been tested with the same company.
How Cat DNA Tests Work
Cat DNA tests work similarly to human ancestry DNA tests. The process involves sequencing a cat’s DNA and looking for genetic markers to determine ancestry and family relationships.
Most cat DNA tests use a cheek swab to collect a DNA sample from the cat. The sample is then sent to a lab for analysis. At the lab, scientists extract and sequence DNA from the cat’s cells to read the genetic code. The cat’s DNA sequence is then compared to breed databases to look for genetic markers associated with specific cat breeds. Some tests look at over 100,000 genetic markers to determine a cat’s ancestry and breed mix.
To find cat relatives, the DNA sequence is checked against a database to look for matching segments that indicate shared ancestry. Closely related cats like siblings or parent-offspring will share large matching DNA segments. More distant relatives like cousins will share smaller matching segments. The more DNA two cats share, the more closely related they are.
The analysis allows the lab to determine the cat’s breed makeup and identify relatives in their database down to the level of siblings or cousins. The results get sent back to the owner to learn more about their cat’s genetic background.

DNA Tests That Find Cat Relatives
Some cat DNA tests like Basepaws and Wisdom Panel offer relative matching features that can identify close family members of your cat. These tests analyze your cat’s genetic profile across thousands of markers and compare it to other cats in their database. If they find cats who share significant amounts of DNA with your cat, they can determine if those matches are parents, siblings, grandparents, aunts/uncles, or cousins. The more DNA two cats share, the closer their relationship.
For example, Basepaws matches cats based on over 150,000 genetic markers and provides percentage match estimates to indicate how closely related two cats are. Wisdom Panel compares over 350 genetic markers and indicates if a match is an immediate family member or extended relative. So while these tests cannot provide an exact family tree, they can determine if your cat has any close relatives in their databases.
The relative matching is only possible if the potential relatives have also been tested with the same company. So the number of identifiable relatives depends on how many users are in their databases. Both companies have tested hundreds of thousands of cats, but many cats will still not have any matches in the system.
Limitations
One of the main limitations of cat DNA tests for finding relatives is that not all cats are in the database. This means that even if your cat submits a DNA sample, there is no guarantee of finding relatives through DNA matching. The database of cat DNA profiles is still growing, so the likelihood of finding relatives improves over time. But many cat owners have still not submitted their cat’s DNA. This can be due to privacy concerns, lack of awareness, or simply not being interested in DNA testing their pet. According to one source, less than 1% of the domestic cat population has been DNA tested as of 2022. So the database coverage remains low compared to the total cat population [1]. With more cat owners participating in the future, the chances of successful cat relative matches could substantially improve.
Privacy Concerns
Some cat owners have concerns about privacy when considering DNA tests for their pets. Sharing a cat’s genetic information raises questions around data usage and security. According to the best cat dna testpurrfection.net, privacy should be a top consideration when choosing a DNA testing company.
Specifically, some owners don’t want their cat’s DNA data shared or sold without their consent. They worry about how the DNA will be used and who will have access to it. There are concerns that data could be leaked or hacked. Some owners simply want to protect their pet’s genetic privacy.
It’s important for cat owners to research DNA testing companies’ privacy policies before using their services. Reputable companies will be transparent about how they use, store and share DNA data. Owners should look for strong security measures and opt-out options for any secondary uses of their cat’s genetic data.
Reliability of Cat DNA Tests
The reliability and accuracy of cat DNA tests varies significantly depending on the specific test and laboratory used. When looking for cat relatives, pet owners must understand that these tests are not 100% perfect. However, many cat DNA tests can reliably identify close relatives with a high degree of accuracy.
According to experts at Fluffytamer, cat DNA tests that look for close relatives like siblings or parents are generally quite accurate when analyzed by a reputable lab like Basepaws or Wisdom Panel. These tests compare specific genetic markers between cats to determine if they share common ancestry. Results can accurately determine if two cats are closely related about 90-95% of the time when optimal samples are provided.
However, as the ancestral relationship gets more distant, the accuracy decreases. Identifying more distant relatives like cousins or second cousins is far less reliable. Factors like poor DNA samples, lab errors, or not having a comprehensive database of cat DNA also reduces the accuracy substantially. Additionally, some tests marketed as “relation tests” may only attempt to identify breed makeup rather than ancestral connections.
In summary, cat owners looking to find close relatives like their pet’s parents or siblings can rely on cat DNA tests to provide useful clues with decent accuracy. But the results should always be considered alongside other evidence, as the tests are not 100% perfect. For more distant ancestral connections, DNA tests become far less reliable (https://fluffytamer.com/cat-dna-tests-accuracy/).
Benefits
Cat DNA tests can provide many benefits for cat owners and their furry companions. One of the most notable benefits is the ability to reunite lost cats with their families. As the ASPCA notes, microchips have certain limitations, but cat DNA tests can provide a more reliable way to identify lost pets and match them with their owners (Source). Services like Basepaws maintain DNA databases that owners can use if their cat goes missing.
Another major benefit is learning more about a cat’s genetic health predispositions. Certain breeds are prone to developing certain conditions, like Maine Coons and heart disease. DNA tests can screen for over 30 genetic diseases and determine if a cat may be at risk later in life, allowing owners to monitor for early symptoms (Source). This empowers owners to provide preventative care and improve their cat’s lifespan.
Cost
The cost of cat DNA tests varies widely from company to company. In general, cat DNA test kits range from approximately $45 to $150 (Source). More expensive options from well-known brands like Wisdom Panel tend to provide more detailed results and information about your cat’s ancestry and traits. Cheaper options may only test for breed. As you’d expect, the more you pay, the more insights you gain about your cat’s genetic profile (Source).
Factors that influence the price include the number of genetic markers analyzed and the amount of information provided about health, traits, and ancestry. Basic breed identification tests are the most affordable, while tests that also screen for hereditary diseases or give percentages of breed mix cost more. Companies also differ in their database size, research, and algorithm accuracy. Sales, discounts, and special offers can reduce costs as well.
Adoption Searching
DNA tests can be a useful tool for finding biological relatives of adopted cats. When a cat is adopted from a shelter or rescue, their history is often unknown. A cat DNA test can potentially connect adopted cats with their biological parents, siblings, or other relatives by identifying shared DNA markers.
For example, the cat DNA testing company Basepaws offers a service called Reunite that allows users to upload their cat’s DNA profile and see if any matches exist in their database. Basepaws claims over 25% of sampled adopted cats have relatives identified through their DNA matching program.[1] By comparing an adopted cat’s DNA to all cats in their system, they can find close or distant relatives based on the amount of shared DNA.
There are some limitations with using cat DNA tests for adoption searching. The databases are still limited, so matches are not guaranteed. Privacy restrictions may also prevent contact with a cat’s biological family. But as more cats are tested, the likelihood of finding relatives generally increases. For adopters motivated to learn more about their cat’s origins, DNA testing offers a useful way to potentially find biological relatives through genetic matching.
Conclusion
In summary, DNA testing for cats can indeed detect genetic relatives, but has some limitations. These tests work by analyzing specific markers in a cat’s genetic code and comparing them to other cats in the database. Close matches likely indicate a sibling or parent-offspring relationship.
However, privacy concerns exist, as some companies may retain or sell genetic data. The tests also have restricted databases currently, so can’t guarantee finding relatives in all cases. Reliability varies between services as well.
Overall, cat DNA tests can be a useful option for those wanting to learn more about their pet’s ancestry and find potential relatives, especially for adopted cats. But consumers should research companies carefully and recognize the current constraints.
The main takeaway is that cat DNA tests do have the capability to identify relatives, but may not always produce definitive answers. As the technology develops further, the ability to find genetic relatives for cats will likely improve.
