I have taken a bite of dry cat food just because I was curious. Not bad. Not good, but not bad. lol
I was discussing this with my mom recently. A can of cat food costs what? Maybe seventy cents if you buy it cheap? For fifty to seventy cents (where I live), you can buy a can of soup (generic soup, like dollar store).
You can live off of Ramon noddles for pennies. There's really no need to live off of cat food.
You could bait the cat in with a can of catfood and then mix him with the Ramon noodles.
