You may think it sounds a little crazy at first, but the best way to save money, is to buy the expensive stuff. I'll give you a few reasons why this is true. The first, is that the high quality foods like Wellness have a much higher nutritional value than something like Iams. This means the cat doesn't need to eat as much to maintain enough calories and vitamins. You can actually feed your cat less, and they will be healthier all around because of it when feeding them a high quality food. There is a trickle down effect of this decision. The next thing you're going to cut down on is litter costs, because a cat that eats less, poops less. Finally, you will save the biggest amount of money on vet bills down the line, because the number one cause of illness in cats is poor diet. I hope this is helpful :)
