I find it easier to place in the medial saphenous vein, and cats tolerate it well. Give intravenous fluids. Normal saline solution is commonly used, but lactated Ringer's solution is also appropriate if severe acidosis isn't present. This is a slower flow rate than often recommended, but it is effective if combined with aggressive enteral feeding. Proceed with enteral feeding.
Nutritional support is paramount to the well-being of patients with renal failure.
A patient in a catabolic state begins to metabolize protein for energy. Enteral feeding supplies food and fluid, greatly shortens the time needed to correct dehydration, helps the cat feel better quickly, and corrects malnutrition. Don't underestimate its importance. Control gastric hyperacidity. In many cats, this does not create vomiting but causes nausea resulting in anorexia.
