My male kitten is acting weird. He is yowling day and night. He has been more affectionate during the last 3 days. He has been trying to "mount" my other cats. I know he needs to be neutered and plan to do so but I have to wait about another 2 weeks according to the traveling clinic that did his first set of shots. I know male cats do not go into "heat" but do they get hormonal? This behavior is keeping me up all night and he's actually getting a bit aggressive. Does anyone know if I really have to wait to get boosters before he can be neutered? Any info or advice is much appreciated.
