So, I'm considering getting a cat. Now, I've never had a cat before (and I don't really work with them in the rescue), so I was wondering about cat food and litter. Is any type of litter better/worse then others? And how much litter do you really use? I'm looking at premium cat foods as well - what should I look for in terms of protein levels, fat levels, etc? What are the best brands/formulas? Are there any ingredients to avoid (like corn in dogs)? I know what to look for with dogs, but this is new to me! I have quite a few local specialty pet food stores around here, and they carry or can order pretty much anything. Thanks for your help!
