Hi and thanks for posting on Petco Pet Education Center, formerly Petcoach! If Milo has stayed for the week with your brother or sisters cats whom Milo has never met before while you were away, it possible those cats did not like Milo very much or became stressed with a new cat in their home. If Milo use to get along with your brother/sister's cat before, perhaps you leaving triggered the stress and aggression of the other cats. Cats do not do well with change and can really become stressed when their owner's habits or environment changes suddenly. It is best is Milo is kept at distance from your brother and sister's cats as much as possible for several weeks and then try slowly reintroducing them with a few short introduction sessions under supervision. Feliway pheromone spray diffusers around the house can work on easing tension. I hope this helps and best of luck to you and Milo!
