From what I have read about kittens, they cannot eat too much because they are growing - and fast! But this 13 week old kitten we have seems to eat A LOT. He is a little piggy! When he's not sleeping, he probably runs to the food bowl every half an hour and eats. Is he gonna get fat? I really don't want to have a fat cat when he gets older! At what age should I limit his food? If he keeps this up into adulthood, he's gonna be one of those tub cats and I really don't want that - it is unhealthy not to mention expensive!
