Medical Conditions

  • Too much vitamin A can lead to poisoning. While somewhat uncommon in North America, vitamin A toxicity is sometimes diagnosed in cats that are fed primarily table scraps. There seems to be considerable variability in how susceptible individual cats are to this problem. It takes a long time for the clinical signs associated with vitamin A toxicity to develop; symptoms do not usually appear until the cat is at least middle-aged.

  • Vitamin D poisoning occurs when a cat ingests a toxic dose of vitamin D. A common source of vitamin D poisoning is when a cat accidentally ingests rodenticides containing vitamin D. The initial clinical signs of poisoning occur anywhere from 8 to 48 hours after ingestion and include depression, weakness, and appetite loss. Vomiting, increased drinking and urination, constipation, and dehydration typically follow these signs.

  • Vomiting may be caused by disorders of the stomach, but is a clinical sign that can occur with many diseases and problems. Different types of vomiting are reviewed. Any required tests are determined based on physical examination of your cat and questions regarding how your cat has been acting and feeling at home.

  • Von Willebrand's disease causes an inability for blood to clot resulting in excessive bleeding. If this disease is suspected, initial screening tests include a complete blood count (CBC), buccal mucosal bleeding time, and a coagulation profile. More advanced diagnostics include assays that assess the quantity and functionality of vWF. DNA testing is available and most commonly used to evaluate animals used in breeding programs.

  • Von Willebrand's disease is an inherited bleeding disorder. Cats with von Willebrand's disease lack von Willebrand's factor, a blood protein that helps platelets adhere to sites of blood vessel injury. Although affected cats have normal platelets, they experience clotting difficulties because their platelets do not properly adhere to injury sites.

  • Cancer is the result of genetic damage to cells. While some breeds may be more predisposed to certain forms of cancer, age-related changes and environmental factors are also often at fault. Some tests can be performed to determine the type of cancer present. Treatment options are available but do not necessarily cure cancer.

  • Cats will always lick, but it is sometimes embarrassing when they lick their private parts. Licking after eliminating is normal; however, if your cat licks more frequently, or you notice other signs such as discharge; swollen or red penis, vulva, or anus; pustules; discoloration of the skin; or if your cat strains to urinate, see your veterinarian for help. Appropriate medical therapy can reduce your cat's discomfort.

  • Regular preventive health care for your cat can increase the length and quality of her life. Healthcare guidelines are established and kept up to date using the most recent evidence-based recommendations including the recommendation that all cats receive a complete veterinary examination at least once a year or more frequently, depending on their individual needs and health concerns.

  • Xanthine bladder stones are an uncommon type of urinary stone that can occur in both dogs and cats. Xanthine is produced when purines (a component of animal proteins) are broken down within the body. Most cats can further break down xanthine into other substances that are easily excreted, but some cats are deficient in an enzyme that is required for this breakdown to occur. These cats develop elevated levels of xanthine in the urine, resulting in xanthine stones forming within the urinary tract. Xanthine urinary tract stones are typically removed surgically. Affected cats require long-term care to prevent recurrence.
