I've taken in a 6 month old kitten who has a funny little disposition but what I'm wondering about is what would be best to feed him. He's an indoors cat and the food that was given to us was the IAMS indoor kitten brand. Now is this good for him (haven't had a problem and we've had him for two weeks) or should I switch him to something different. Also, if it makes a difference, for a kitten he's not very active instead of playing with the toys we got him he lays in my chair with me and naps. Is that a normal thing?
