You're 100% right. I'll add it right away. :)
Edit: I had something like this as the last "cat tip", but I rewrote it a bit and moved it to the foods section:
Feed your cat food (both dry and wet) that is as high in meat content (as a percentage) as possible, without cereals, sugars, salt, fruit or animal subproducts. Cats are sometimes allergic to chicken, while more exotic meats like ox, rabbit, boar, etc. are usually better tolerated.
I tried to make it short and to the point so that people don't tl;dr it. :D
