Where healthy eating is REALLY expensive is cat food. I buy the best cat food on the market, from Amazon. The brands I buy are BFF (Best Feline Friend), Weruva, and Before Grains. Chicken, quail, tuna, tilapia, salmon, 100% animal protein as appropriate for cats. No fillers - no starches such as pasta or rice, no nothing. 100% wet food. I also give them human food: yogurt, kefir, and rotisserie chicken. Wet food is always more expensive than dry food. But it is better for the kitties. And I think that ultimately when my cats get old I will recoup some of this cost via not having to pay veterinarian bills for treatment of diseases that are caused by substandard feeding practices, such as diabetes and kidney disease. But I can tell you that buying crap is considerably cheaper than buying 100% carb-free wet food.
