Yes, if you eat catfood and saltines.
Cat food can be quite expensive. I'd go with chicken thighs. You can get a family size pack for about $3. They taste a lot better too.
And instead of saltines, go with those big 5 pound bags of peanuts. Peanuts are more filling and pack way more nutrition.
So chicken and peanuts! Now that's a much tastier retirement. And throw those peanut shells to the floor. You are retired now. Who you trying to impress?
