Cat gravy??

i want to make for my kitties cat gravy, they absolutely love wet food with a lot of gravy, such as the fancy feast stuff.

anyone got any advice how to make home made cat food or gravy?

I was surprised how over here they sell fresh meat for pets, but the kitties dont really like it as it tends to be mushed up liver and left over organs.
so i thought about cooking it with no salt or spices and just making a heap of gravy with it!
