Cats have three main blood types: A, B, and the rare AB. Type A is most common, Type B varies by breed and geography, and AB is very rare. Knowing your cat's blood type is vital for safe blood transfusions and preventing neonatal isoerythrolysis.
Like humans, cats have different blood types that are genetically inherited. The three primary feline blood groups are A, B, and AB. Understanding these is crucial for safe veterinary procedures, especially blood transfusions and managing breeding risks.
Mismatched blood transfusions in cats can cause severe, often fatal, immune reactions. Type B cats have strong antibodies against Type A blood, making even a first transfusion dangerous. Type A cats have weaker antibodies against Type B, but reactions still occur.
Without proper typing, you're risking your cat's life during what should be a life-saving procedure. Continue reading to understand the specific risks and how modern veterinary medicine prevents these terrifying transfusion reactions through simple testing protocols.
Type B cats pose the greatest concern as they naturally possess strong anti-A antibodies that can cause immediate hemolytic reactions. Even a first-time transfusion with Type A blood can be fatal. Type A cats have weaker anti-B antibodies, but repeated exposure still causes significant reactions. The rare AB type lacks both antibodies, making them universal recipients but extremely difficult blood donors to find. Veterinary clinics now prioritize blood typing as standard pre-transfusion protocol, with many keeping typed donor lists for emergencies. As a leading veterinary diagnostics manufacturer, we've seen how proper typing transforms transfusion safety in clinical practice.
When a Type B queen mates with a Type A tom, kittens inheriting Type A blood can develop neonatal isoerythrolysis. The queen's colostrum contains anti-A antibodies that destroy the kittens' red blood cells when they nurse during their first days of life.
Watching newborn kittens fade away despite appearing healthy at birth is devastating for any breeder. The tragedy is that this condition is entirely preventable with simple pre-breeding testing. Read on to learn how strategic breeding decisions can eliminate this risk entirely.
The inheritance follows simple Mendelian genetics where Type A is dominant over Type B. However, the AB type involves a different genetic mechanism. Responsible breeding requires testing both parents before mating. Type B queens should only be bred to Type B toms to completely eliminate NI risk. For mixed matings that have already occurred, breeders can implement strategies like blood typing newborns and cross-fostering or artificial feeding for at-risk kittens during the critical first 72 hours. Many reputable pet diagnostics provider companies offer breeder testing programs to support these vital preventive measures.
Type B blood occurs with much higher frequency in specific purebred cats. Breeds like British Shorthairs, Devon Rex, and Turkish breeds show particularly high percentages. Geographic variations also exist, making testing essential even within high-prevalence breeds.
Assuming your purebred cat has the more common Type A could lead to tragic consequences during emergencies or breeding. The distribution patterns reveal fascinating genetic histories. Discover which breeds carry the highest risks and why geographic testing remains crucial despite breed tendencies.
The high prevalence in certain breeds suggests genetic bottlenecks and founder effects during breed development. Geographical variations are equally important - Australian and Swiss cat populations show higher overall Type B percentages than North American random-bred cats. This means a domestic shorthair in Switzerland has significantly higher Type B probability than one in the United States. These patterns underscore why assumptions based on breed alone are insufficient. Every cat deserves individual testing, particularly those from high-prevalence breeds or regions. As a trusted veterinary diagnostics supplier, we provide testing solutions that account for these variations in clinical and breeding settings.

Why is knowing your cat's blood type critical for transfusions?
Problem: Your cat needs emergency surgery or has severe anemia. Agitation sets in as you worry about complications. The solution? Pre-transfusion blood typing prevents life-threatening reactions, ensuring donor blood matches your cat's type for a safe procedure.Mismatched blood transfusions in cats can cause severe, often fatal, immune reactions.

Understanding Transfusion Risks and Compatibility
The risks associated with mismatched feline blood transfusions stem from naturally occurring alloantibodies. These antibodies can immediately attack and destroy transfused red blood cells that don't match the recipient's type. The consequences range from mild fever to rapid death.| Recipient Blood Type | Can Receive From Type A | Can Receive From Type B | Can Receive From Type AB | Risk Level |
|---|---|---|---|---|
| Type A | Yes (Ideal) | No (High Risk) | Yes (Acceptable) | Low with proper matching |
| Type B | No (Severe Risk) | Yes (Ideal) | Yes (Acceptable) | High if mismatched |
| Type AB | Yes (Acceptable) | Yes (Acceptable) | Yes (Ideal) | Universal recipient |
Type B cats pose the greatest concern as they naturally possess strong anti-A antibodies that can cause immediate hemolytic reactions. Even a first-time transfusion with Type A blood can be fatal. Type A cats have weaker anti-B antibodies, but repeated exposure still causes significant reactions.

How does blood type affect breeding and kittens?
Anxiety mounts when your pregnant queen gives birth to seemingly healthy kittens that suddenly weaken and die within days. This heartbreaking scenario, called neonatal isoerythrolysis, is completely preventable with proper blood type knowledge before breeding.When a Type B queen mates with a Type A tom, kittens inheriting Type A blood can develop neonatal isoerythrolysis.

Breeding Strategy Based on Blood Types
Neonatal isoerythrolysis (NI) represents a significant concern for cat breeders worldwide. The condition occurs due to the maternal-fetal blood type incompatibility, where antibodies in the queen's milk attack the kitten's red blood cells. Understanding the inheritance patterns helps breeders make informed decisions.| Breeding Pair Combination | Possible Kitten Blood Types | Risk of Neonatal Isoerythrolysis | Recommended Action |
|---|---|---|---|
| Type A x Type A | 100% Type A | None | Safe breeding |
| Type B x Type B | 100% Type B | None | Safe breeding |
| Type A x Type B | 100% Type AB (if parent carries recessive) | High if queen is Type B | Type B queen should not be bred to Type A tom |
| Type AB x Any | Varies based on mate | Low to moderate | Test kittens and monitor |
The inheritance follows simple Mendelian genetics where Type A is dominant over Type B. However, the AB type involves a different genetic mechanism. Responsible breeding requires testing both parents before mating. Type B queens should only be bred to Type B toms to completely eliminate NI risk.

Many reputable pet diagnostics provider companies offer breeder testing programs to support these vital preventive measures.
Which cat breeds have higher prevalence of Type B blood?
Shockingly, certain purebred cats have over 40% prevalence of Type B blood compared to the 5-10% in random bred populations. This genetic concentration creates significant breeding and medical challenges that owners of these breeds must understand for proper care.Type B blood occurs with much higher frequency in specific purebred cats. Breeds like British Shorthairs, Devon Rex, and Turkish breeds show particularly high percentages. Geographic variations also exist, making testing essential even within high-prevalence breeds.

Breed Prevalence and Geographic Distribution
The distribution of feline blood types isn't random across breeds or geography. Certain breeds show remarkable concentrations of Type B blood, while geographical isolation has created distinct regional patterns. This information helps veterinarians assess statistical probabilities before testing and informs breeding programs.| Cat Breed/Group | Type A Prevalence | Type B Prevalence | Type AB Prevalence | Geographic Notes |
|---|---|---|---|---|
| Domestic Shorthair (US) | 97-99% | 1-3% | <0.1% | Varies by region |
| British Shorthair | 40-60% | 40-60% | 1-2% | Consistently high Type B |
| Devon Rex | 55-65% | 35-45% | 1-2% | High Type B prevalence |
| Turkish Van/Angora | 35-45% | 55-65% | 1-2% | Among highest Type B |
| Abyssinian/Somali | 85-90% | 10-15% | <1% | Moderate Type B |
| Siamese/Oriental | 95-100% | 0-1% | <0.1% | Virtually all Type A |
The high prevalence in certain breeds suggests genetic bottlenecks and founder effects during breed development.
