DNA Testing Bonded Rescue Cats on a Budget

Testing a bonded pair of rescue cats at the same time is a smart move — you can compare their backgrounds side by side and often save a bit versus buying separately. I should be upfront with you: cat DNA testing has come a long way, but it's behind dog testing in terms of breed database depth. You'll get useful breed composition results and some health marker screening, but the health side varies between providers and isn't a substitute for vet bloodwork. Are you mainly curious about their breed backgrounds, or is the health screening equally important to you? And do you have a rough idea of their colouring or coat type — that sometimes helps set expectations for what the results will show.

That's a really common situation with rescue cats and honestly a fun one — tabby colouring can mask all sorts of breed mixes. For two kits on a budget, Basepaws is the brand I'd point you toward. Their Breed + Health test is the most established cat-specific DNA test available in the UK, with a decent breed database covering 21 breed groups. The health screening covers over 40 genetic conditions too, so you're not just getting breed info. At roughly £60–70 per kit, buying two is still more affordable than most dog DNA testing for a single animal. The results typically take 4–6 weeks and come through a clear app. I wouldn't recommend the cheaper generic options — the cat breed databases on those are thin and the results tend to be vague to the point of not being very meaningful.

Basepaws does run multi-kit discounts periodically — it's worth checking their own website directly as they sometimes do buy-two deals. On Amazon UK they're usually listed individually, but the pricing fluctuates and you can add both to your basket to see if a bundle discount applies at checkout. I'd check both the Amazon listing and the Basepaws site on the same day and go with whichever is cheaper. Either way, two Basepaws Breed + Health kits is still the recommendation — the breed coverage and the app experience are genuinely better than the alternatives at this price point for cats.

Not necessarily — and this is actually one of the more interesting parts of testing littermates or cats from the same rescue intake. Even full siblings can show different breed percentage breakdowns because they inherit different combinations from the same parents. So it's quite likely you'll see variation, sometimes surprisingly different results. If they are closely related, the results will probably share some of the same breed markers but the proportions can differ noticeably. Testing both separately gives you the full picture for each cat as an individual, which matters if you ever share health information with your vet.
