What do big domestic cats have in common?

Large cats, such as the Turkish Van, British shorthair, and Savannah cat all have wild cats among their ancestors. This origin story is what many attribute unique breed elements to, such as their large size, fur patterns, and interesting vocalizations..

Common wild cats that can share genetics with big domestic house cats include:

  • Servals. These big wildcats live in the deserts of South Africa and remain the only member of the genus Leptailurus.
  • Asian leopards. These cats are nocturnal hunters that live across terrains in many Asian countries, such as China, Pakistan, and the Korean Peninsula.
  • African wildcats. Domestication of this breed is thought to have started about 10,000 years ago by many—a move which may have influenced many big cat breeds today.

What health problems are common in large domestic cats?

While large or hybrid cats can make great family pets for you and your loved ones, they can be predisposed to certain health and weight conditions. Pet parents can prepare by acknowledging these possible health problems ahead of time, taking preventative steps to care for this special member of the family.

We’ve summarized possible large-cat medical concerns, as identified by the American Association of Feline Practitioners (AAFP) below:

  • Cancer. Unfortunately, large cats (like many others) may be predisposed to cancer. Some breeds, such as Siamese cats, may be predisposed to certain types of cancer, like adenocarcinoma. Your vet can assess your cat’s risk profile for cancer, evaluating them for cancers that can be caused by feline leukemia virus (FeLV) or other possible causes. Treatment is available, possibly ranging from chemotherapy and radiation to surgery.
  • Hip dysplasia.  (Trusted Source) Large cats may experience hip or joint dysplasia, possibly as a result of their big stature, genetic profile, and longer-than-average bones. This condition is thought to occur when the femoral head, or tip of the leg bone that meets the hip, doesn’t articulate properly in the hip joint, which can cause pain and mobility loss. Your vet can help, intervening with physical therapy, anti-inflammatory medication, or surgery if needed.
  • Diabetes. Diabetes in cats can look like it does in humans—occurring as a response to a lack of insulin or faulty release of insulin, which can be caused by weight-related insulin resistance. While all cats can experience this, big cats might as a result of mismanaged diets for their size, or a genetic predisposition in the bloodline. Your vet can offer insight here, including dietary recommendations for larger cats, lifestyle changes, and medication if needed.
