Hepatic lipidosis also known as fatty liver syndrome can occur when transitioning your cat to a new diet. Cats unlike dogs have a very addictive nature and it can be tricky to get them to eat a new diet when they are basically addicted to their current diet. In some cases the cat will starve itself resulting in liver failure. Even refusing to eat for a few days can put them at serious risk. It is essential to work with a feline nutritionist to prevent this problem from occurring.
