hi.. i have a cat, i just call her meow. she's just an ordinary tabby. will upload some pics soon. i don't see any thread discussing cat food so post my question here. i wonder what kind of cat food is best? i normally feed her with cat biscuit and occasionally some tuna (cat food one) usually go for whiskers brand. how do we know if the cat food is actually any good for our creatures?

another question: why is she always shedding a lot of hair?
