Back to your original question, I personally think that wet food is better than dry food. Especially if you plan to feed only one. All-dry diets can lead to loads of problems including cystitis. You can feed a half/half but I give them all wet. For brands, Friskies and Fancy Feast are 2 cheap options. People say that they're low quality, but I've been feeding my cats those all the time they've been with me, with no health problems. However, the Friskies "Classic Pate" are the only ones you should get, the "Tasty Treasure", "Grilled", "Sliced" ones are not as nutritionally good. I get Friskies 5.5 oz cans, 5 for $3 and Fancy Feast 3 oz cans, 5 for $3.75. Fancy feast is the higher quality one though. Wellness is an expensive, but high quality brand. Sheba is also decent.
