Vascular tumors of the skin develop from the blood vessels of the skin. These tumors may arise anywhere on the body and appear as a firm and raised lump on or under the skin. Hemangiomas may ulcerate and bleed; hemangiosarcomas may bleed into the surrounding tissues. This type of tumor is typically diagnosed via a tissue biopsy or surgical removal of the entire tumor. Surgery is the recommended treatment for vascular tumors of the skin.

Vestibular disease is when a cat suddenly develops incoordination, falling or circling to one side, involuntary darting of the eyes back and forth, a head tilt, and often nausea or vomiting. Most cases are idiopathic, meaning the exact cause is unknown. Idiopathic vestibular disease is a short-term, self-resolving condition with a good prognosis.

Feline viral testing typically encompasses testing for feline leukemia virus (FeLV), feline immunodeficiency virus (FIV), and coronavirus which causes feline infectious peritonitis (FIP). Testing for FeLV and FIV is recommended to detect underlying causes to illness, to screen apparently healthy cats who may have been exposed to the viruses, and to identify carriers of the viruses prior to introducing cats into a household of other cats. FIP testing is somewhat more problematic.

Testing for FeLV is recommended to detect underlying causes to illness, to screen apparently healthy cats who may have been exposed to the viruses, and to identify carriers of the viruses prior to introducing cats into a household of other cats. Testing protocols are discussed. Vaccination against FeLV will not affect the outcome of a cat already infected with the virus nor will it affect testing.

Visceral vascular tumors are tumors which arise from blood vessels. The main tumor types are hemangiosarcomas (cancerous) and hemangiomas (benign). The clinical signs vary depending on the location of the tumor. Surgery is the recommended treatment option. Given the highly metastatic nature of hemangiosarcoma, chemotherapy is also recommended.

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.

Vitamin D poisoning occurs when a dog ingests a toxic dose of vitamin D. A common source of vitamin D poisoning is when a dog accidentally ingests rodenticides containing vitamin D. Another source of vitamin D poisoning is the accidental ingestion of certain human medications.

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.
