My Rooney is 18 years old,he is a m/c and prefers the indoors.Only will venture out in summer if we are sat in the garden.He is adorable boy,loving,he sleeps at the top of my pillow at night but before we settle down will [park] himself between my husband and myself they can be possessive.I am glad he is an indoor cat because of the grooming[they need it every week] but if you do it from a kitten there should be no problem.I have two other cats but Rooney is ok with them just knows he is a cut above lol.I can honestly say they are wonderful naturered cats so gentel granted they are large and I must add can be very vocal,they will let you know what they want and will not quit until they get their own way.As regards the food he eats the same as the other two,tinned cat food,fresh cooked chicken, fish as you can see my three are very spoilt but well worth it.Good luck ,don't hesitate to ask me anything about them.
