I used to give mine Senior food, but then changed to high meat content foods that dont come in that - although HiLife do a Senior pate, 3 flavours, all meat. The main thing to watch with senior food is that it is lower in calories (as oldies are more sedate and need less calories), so if you have one that is on the thin side, it isn't recommended. I currently use a mix of dry though, they have adult and senior, but prefer the adult!!
