Hepatic Lipidosis Most common form of severe liver disease in cats. Most often seen in obese cats suddenly subjected to dietary deprivation. May also be associated with diabetes mellitus, drug injury and toxicity. Thedisease seems to result from the sudden mobilisation of the bodies fat stores which quickly overwhelms the liver's ability to process the raw fat into useful nutrients. The fat accumulates in the liver rapidly and causes acute liver failure. The end result is a swollen, greasy liver which is fragile and yellow to see. The cats present with complete lack of appetite and many signs of acute liver failure. Treatment is based on the provision of a highly nutritious diet to provide the energy required to run the body, stop the ongoing mobilisation of the fat stores, and drive the liver to decrease the fatty accumulation in the liver. Treatment is difficult and a long process.
Transdermal patches (adhesive patches placed on the skin) may also be used to deliver a steady dose through the skin and into the bloodstream. Testosterone-containing creams and gels that are applied daily to the skin are also available, but absorption is inefficient (roughly 10%, varying between individuals) and these treatments tend to be more expensive. Individuals who are especially physically active and/or bathe often may not be good candidates, since the medication can be washed off and may take up to six hours to be fully absorbed. There is also the risk that an intimate partner or child may come in contact with the application site and inadvertently dose himself or herself; children and women are highly sensitive to testosterone and can suffer unintended masculinization and health effects, even from small doses. Injection is the most common method used by individuals administering AAS for non-medical purposes. 
Epidural steroid injections are generally very safe, but there are some rare potential complications. One of the most common risks is for the needle to go too deep and cause a hole in the dura, the tissue that surrounds the spinal cord and nerve roots. When this occurs spinal fluid can leak out through the hole and cause a headache . This headache can be treated with bedrest, or with a blood patch. A blood patch involves drawing some blood from the vein and the injecting it over the hole in the dura. The blood forms a seal over the hole and prevents any further fluid from leaking out.
