I think they just have the one Ninja blender essentially, just comes with slightly different shit. You can still buy that vintage blender on eBay, it's less than the Ninja.

The simplest form of cat food is mostly chicken with a little liver thrown in and a vitamin supplement. There's various things you can add in, fish oil, eggs, dry milk powder, and even some fruits and veggies like apples, cooked potatoes, cooked sweet potatoes, carrots, seaweed. Cats can't utilize vitamins from veggies efficiently, but most people think they shouldn't ever eat it and that's not true, in the wild cats consume their prey's stomach contents. It should never be a large part of their diet. Anyways, you just blend it all together with just enough water to make it work. Makes a thick meat slushy.

Making cat food is more expensive than buying it, and it is absolute hell on a blender. I don't make it anymore because Gizmo prefers his chicken by-product and corn meal bullshit food, but when my last cat was dying it was all she could eat.

I probably have a recipe somewhere, I'd have to look for it.
