IMHO, wet food is better. It might be extra work, but having cats is extra work, and responsibility. You shouldn't shrug off whats best for what is easiest. Cats are carnivores and dry food is full of fillers and very little meat, even the best dry food is not the same as meat. Many people do give home prepared food, now that is alot of work. But a good premium wet food is good and easy. It is not alot of work to open a can 2-3 times per day and dump into a bowl. In the wild cats do not go around looking for dry kibble they eat MEAT. Its really up to you what you feed your kitties, but wet food is better for cats, and they are less likly to become obese. Not all cats, but alot of cats become obese from free feeding on dry food, especially if they are fixed. Dry food is full of carbs, and just like humans can gain weight, which in turn can lead to diabetes. It does not hurt to feed dry food in combination of a mostly meat diet, like if you leave during the day, you can leave out dry, but IMO I think you should keep the dry to a minimum. My cat from the past became obese from free feeding, and it became more work when we had to put her on a diet, she was limping and could not groom herself. I have learned from my mistakes and My cat Buddy is on a wet only diet on Nutro Kitten, and he is happy and healthy. You should also feed kitten food until they are 1 year old.
If you do decide to do both, wet food 2x per day 1 in the morning and 1 at night, dry during the day. Kitten only food until 1 year old, they need the extra nutrients since they are growing!!
