DNA test for a 14-year-old mixed-breed cat

A 14-year-old mixed-breed cat — that's a wonderful age, and it's completely understandable to want to know more about where she came from and whether there are any genetic factors worth keeping an eye on at this stage of her life. DNA tests for cats have come on a lot in the past few years. They can give you a genuinely interesting breakdown of breed ancestry and flag certain inherited health markers — but I want to be upfront: the health screening side is more useful as a conversation-starter with your vet than as a diagnostic tool, especially for a senior cat where regular blood panels and check-ups will catch far more than any DNA test. Is your main curiosity about her breed background, the health genetics, or both — and do you have any clues at all about her background, or is she completely unknown?

Those physical traits are really interesting clues — tufted ears and a bushy tail point strongly toward some Maine Coon or possibly Norwegian Forest Cat ancestry, both of which do carry specific health considerations worth knowing about. For a cat like yours, I'd recommend Basepaws Breed + Health DNA Test. It's the most comprehensive cat-specific DNA test available in the UK, covering breed ancestry across dozens of cat populations and screening for over 40 genetic health markers, including HCM (hypertrophic cardiomyopathy) which is particularly relevant if there's Maine Coon in her background. The results come with a clear report you can share with your vet. Can I ask — is she currently under regular vet monitoring for her heart and kidneys at her age? Because the DNA results will land differently depending on what her vet already knows.

Not worried, but informed is exactly the right word. If the Basepaws test does show significant Maine Coon ancestry, HCM is worth raising specifically with your vet — it's common in that breed and can develop silently. A cardiac ultrasound isn't routine but it's not expensive either, and knowing the genetic background gives you a concrete reason to ask for one rather than just going on instinct. The DNA test won't tell you whether she has HCM right now — only imaging can do that — but it gives you the genetic context to have a more targeted conversation with your vet. At 14 that kind of proactive information is genuinely useful.

Yes, just a simple cheek swab — you rub it inside her cheek for about 30 seconds, seal it in the tube provided, and post it back. Most cats tolerate it fine, especially if you do it when they're relaxed or just woken up from a nap. Results typically come back within 4 to 6 weeks. The report is detailed and well laid out — breed percentages with explanations of each group, the health marker results flagged clearly as detected or not detected, and trait information. At her age the health markers are the most practically useful part, and that's exactly what you're after.

Just a couple of things worth knowing: make sure you swab before she eats or drinks if you can, as food residue can affect sample quality — though it rarely causes a test failure. Keep the results in perspective: a genetic marker for a condition means elevated risk, not certainty, and the absence of a marker doesn't mean a condition can't develop — especially at 14. Share the full report with your vet rather than just the headlines. And honestly, even if the health panel comes back clear, the breed breakdown alone tends to be a genuinely satisfying thing to know about a cat you've had for years. I hope she surprises you.
