The cat is not a small dog: Ten differences in feline and canine oncology Academic Article uri icon


  • This paper focuses on interspecies differences in the prevalence and biological behavior of selected neoplasms of dogs and cats. In many instances the naturally occurring neoplasms of dogs and cats exhibit species-specific biological behavior. In contrast to dogs, bladder tumors occur infrequently in cats and are often surgically resectable. Feline thyroid tumors are usually benign and hyperfunctionally leading to a clinical syndrome of hyperthyroidism. Digital metastasis of primary lung carcinomas causes lameness in cats, but has not been reported in dogs. The vast majority of breast cancers in cats are malignant. Basal cell tumors represent a large percentage of melanotic tumors and lymphoma is the most common spinal tumor of cats. In contrast to canine osteosarcoma, appendicular osteosarcoma in cats is often curable with limb amputation. An appreciation of these differences is critical so that clinicians may accurately communicate prognostic information and treatment recommendations to their clients.
