Understanding the American Bobtail cat health and care

Quick answer

The American Bobtail is a spirited and affectionate companion known for its unique tail and intelligence. While generally robust, the breed has a recognised tendency toward hip dysplasia, patellar luxation, and hypertrophic cardiomyopathy. Owners can support their cat's health by maintaining a lean body condition and providing consistent mental enrichment to keep them active.

Hip Dysplasia

Hip dysplasia is a condition where the hip joint does not fit together perfectly, which can lead to discomfort as the cat moves. This is a recognised tendency in the breed. At home, you might notice your cat hesitating before jumping onto high surfaces, showing a reluctance to climb stairs, or appearing stiff after a long nap. You may also observe a swaying gait or a noticeable decrease in their usual playfulness.

When you bring your cat to the clinic, the veterinarian will perform a physical examination to check for pain or reduced range of motion in the hind limbs. If the vet suspects this condition, they will use X-rays to look at the structure of the hip joints. While this is a recognised tendency, how this passes down is not settled. The best way to support a cat with this condition is to keep them at a healthy weight to reduce the load on their joints.

Patellar Luxation

Patellar luxation occurs when the kneecap moves out of its normal groove. This is a recognised tendency in the breed. You might first notice this at home if your cat suddenly skips a step while walking or holds one of their back legs up for a few moments before returning to a normal gait. Some cats may show a sudden, brief vocalization when the kneecap shifts.

Your veterinarian will assess the stability of the kneecap during a routine physical exam. By gently manipulating the leg, the vet can determine if the patella moves out of place. In many cases, this is a mechanical issue that the vet can grade based on how easily the kneecap luxates. Because this is a recognised tendency rather than a proven one, it is helpful to monitor your cat for any changes in their walking pattern and report them early. Keeping your cat lean is vital, as excess weight puts unnecessary stress on the joints and can exacerbate the instability.

Hypertrophic Cardiomyopathy

Hypertrophic cardiomyopathy is a condition where the heart muscle becomes abnormally thick, which can affect the heart's ability to pump blood efficiently. This is well recognised in the breed. The challenge with this condition is that cats are excellent at masking symptoms. You might notice your cat breathing faster than usual while resting, appearing lethargic, or showing a sudden lack of interest in their favorite activities. In some cases, the first sign may be a sudden onset of weakness.

Your veterinarian will listen to your cat's heart with a stethoscope to check for murmurs or abnormal rhythms. If the vet hears something concerning, they will likely recommend an echocardiogram, which is an ultrasound of the heart. This test allows the vet to see the thickness of the heart walls and the efficiency of the blood flow. Because this is well recognised in the breed, regular wellness exams are essential for early detection.
