How Much Should A 4 Month Old Kitten Weigh?

My cat is a 4 month old kitten, he’s been very healthy and I’ve been feeding him with Purina Cat Chow dry food. At first his growth seemed to be slower than normal but now that he seems to have caught up all the way. He weighs 5 pounds, 3 ounces at the time of writing this post. Do you think that is normal for an average weight for a 4 month old cat? And how much should my cat weigh in order to be considered “healthy”?
