I am Wesley, the famous student cat!

Dear George,
I just came across your blog and I think I'm in the right place to get advice. I'm a rescue and I have recently adopted a human kitten not knowing that he attends university in a different city. As he didn't want to leave me behind he took me with him to the student camp where he lives. So I became instantly famous (even if some would call me infamous) and very, very spoiled. Just imagine having at least 4 big guys, all football players, taking care of me!
But, I need your expertise in nutrition as I want to make sure that I eat right for my age  and all my adopted human kittens eat right too (they are athletes after all and probably need more protein, etc). I'm not worried about food when we have a school break as we always go back home to our human mommy and she cooks well! So....dry or wet food for me? What about treats? Should I share food with my human kittens? They eat mostly meat sandwiches. Or....should I just stay home with Mommy?
In gratitude 
Wesley
Dear Wesley, 
I do envy you. Four big football guys all taking care of you! Lucky old you. I bet that they are real softies.
Nutrition. Adolescent humans usually eat very badly indeed and meat sandwiches are not the ideal cat food. (Nor are they the ideal human food, which should contain fruit and vegetables not just meat and bread). By all means eat a bit of sandwich when you fancy it. A little of what you fancy does you good, but try and get more of the meat and less of the bread! Don't let them fob you off with the outside crusts.
Mouse sandwiches would be a great idea if you could purrsuade your football guys to go in that direction. Could you tempt them by catching one and presenting it to them? Raw mouse is probably the best natural food of all but for some reason, humans are squeamish about feeding them to us. And they don't seem able to produce tinned mouse.
Wet food or dry food? Wet food is great but not ideal for teeth. Dry food can lead to a cat being dehydrated unless they have the chance to drink whenever they want but is better for keeping your teeth clean. Tell your human to put out two bowls in two different locations so you always have a choice.
If you have a cat flap I recommend wandering down the street, and sampling various houses to see if the humans there offer a better brand of cat food. If you are an indoor-only cat it's trickier. Train your human to buy the brand you prefer by purring loudly when you get it. When you get an inferior brand, look at it disdainfully, then walk away. Or take a few mouthfuls and then try to cover it up, like you would cover up the contents of a litter tray.
This usually makes your human feel guilty and we cats make guilt work for us. 
Yours enviously,
George

PS. I can't read ingredients on cat food containers. Celia can read them but says she can't understand them. All the percentages depend on the amount of water in the food and she can't work out what the ingredient "ash" means.
