I agree with the advice of others--stick to good quality dry food. Once they get addicted to the canned food, you will be stuck with it--and all the mess and smell that it entails.

Also, if you can train them to have their toenails clipped regularly when they are young, and train them not to scratch the furniture, you can avoid having them declawed. My cat is also an indoor cat, and even at a year old, I got him to accept the clipping (I just use normal nail clippers, and the same precautions pertain as a dog--don't cut their quick, or it will hurt like heck and they will everafter hate it.) I do it every couple of weeks.

I also got several scratching posts and gave him plenty of praise for using them. I put one against the arm of the sofa to prevent him from going at that. So far, after about 3 years, I've only noticed one nail hole in the leather chair.

I must admit I am opposed to declawing if you can possibly avoid it, although I admit that sometimes there is no alternative.

My boy also is very vocal, and was an outdoor cat when we got him, which made it very tough. He still gets "the call of the wild" twice a year, despite being neutered, and wants to go out and get the girls, howling around the house late at night. Hope he shuts up before we move into out condo in 2007! Until then he gets to watch the bird-feeder all day, which helps to keep him content.
