I have three cats one of them is a m/c they are wonderful cats so loving and gentle they make good indoor cats and because of their nature would have no problems ,my other two tend to bully a little bit if given the chance, but he is my baby and goes to bed whilst the other two guard the landing at night,he sometimes ventures outside but likes his comfort too much and prefers the settee lol. He will still need all his injections ect for all he does not go out pedigrees are soon to catch things as you will know.good luck to your pal he/she will not regret it.
