I am fostering a 10 week old kitten, tested negative for feline leukemia (but littermates are positive). He's the sweetest kitten, is very cuddly, walks around the house with me (and that's just after 3 days), always wants to be with me, but doesn't really play. I have the feathers, the balls, the mice, but he's not interested in them.
Is this typical? He seems healthy in other ways (eating, drinking, litter boxing).
