This is a specific conversation about Pet DNA tests — what they can and can't tell you — ask about yours and get one honest answer for your exact situation.

Your vet has flagged Glycogen Storage Disease Type IV — that's a smart catch, because GSD IV is a serious inherited condition that shows up specifically in Norwegian Forest Cats, and testing for it before symptoms appear is genuinely worthwhile. Consumer DNA kits have caught up here: a few now include this marker, so you don't necessarily need to go through a specialist lab. Is your cat currently showing any symptoms, or is this purely precautionary? And just to make sure I point you to the right kit — are you mainly after the GSD IV result, or would broader health and breed screening be useful too?
It's completely precautionary, she's healthy as far as we can tell. I'd love the broader health screening too if it's available — I wasn't even sure consumer kits tested for GSD IV.

Good news: Basepaws does include GSD IV in their health screening panel, which makes them the clearest consumer option for Norwegian Forest Cats specifically. Their Breed + Health kit covers over 40 genetic health markers including GSD IV, plus a full breed breakdown — you swab at home and post it back. One honest caveat: for a clinically actionable result your vet will act on (say, if you were breeding her), some vets prefer a result from an accredited diagnostic lab like Laboklin. But for a healthy cat where you want peace of mind and solid information, Basepaws is genuinely good and the GSD IV marker is specifically listed. I'd go with the Basepaws Breed + Health Cat DNA Test — it's available on Amazon UK, arrives quickly, and the report is detailed enough to share with your vet.
That's really helpful. What does a positive GSD IV result actually mean in practice — is it a death sentence?

Not automatically, no — and this is an important distinction. GSD IV follows an autosomal recessive pattern, so a cat needs two copies of the mutated gene (homozygous) to actually develop the disease. A cat with one copy (a carrier) typically lives a completely normal, healthy life and won't develop GSD IV themselves. If Basepaws returns a 'carrier' result, it's relevant if you ever bred her, but it doesn't affect her health at all. A homozygous positive is more serious — those cats can develop muscle weakness and neurological symptoms, often in kittenhood, which is why at four years old and healthy, a homozygous result would actually be quite unlikely. But knowing either way is useful information.
That's reassuring. Is the Basepaws kit easy to use? My cat is not exactly cooperative.

It's a cheek swab rather than a blood draw, so no needles involved — that's the main thing. You rub a small swab inside the cheek for about 30 seconds. For a wriggly cat, the trick is to do it when she's calm and slightly drowsy, maybe after a meal. The kit comes with clear instructions and two swabs, so you get a second attempt if the first one goes badly. Results typically come back in 4–6 weeks. Honestly, it's one of the easier home tests — much simpler than trying to collect a urine sample.
Perfect, I'll order the Basepaws kit. Should I let my vet know I'm doing this, or just share the results when they come back?

Worth a quick mention at your next appointment, mainly so they know what's coming and can contextualise the result properly. Some vets are very familiar with Basepaws; others less so. If the result does show carrier or positive status, your vet may want to follow up with a confirmed diagnostic test from a veterinary genetics lab before making any clinical decisions — that's standard practice and not a reflection on the kit's quality, just how clinical genetics works. But for a precautionary screen on a healthy cat, Basepaws gives you genuinely useful data and a solid starting point.
