Well, since the OP asked for crock pot ideas, I'll skip the cat food debate and offer up an easy one that is always popular. I have two versions, quick and easy and a little upgaded.
If you have time, I cube some country style pork ribs then flour them and brown them. dice and saute some onion. mince some garlic and dice up a few green chilis. ( as far as quantity, go to your tastes ) Put all of this in your crock pot and dump a large can of green enchillada sauce in. Cook all day on low or about 4 hours on high. After that, you can thicken it with a rue or cornstarch and serve over rice.
quick version, just put the whole boneless country style pork ribs in the pot, put in some onion powder and garlic powder and pour the can of green enchillada sauce in. when done, shred the pork with a fork.
also works with chicken if you prefer.
