There are so many different opinions on this, it is honestly a minefield! I have come to the conclusion that I go with what makes the cats happiest. Mine are all slllooooooowwww eaters so have found when I have tried (very hard!) to feed just two meals that mine pick at it and then we end up with wasted food and wingey cats not long later. Mine genuinely do like to graze so I feed two smallish wet meals, morniing and night and then measured dry is down for them to graze on in between. They don't scoff it as it's available as and when they want it.
All of our households run slightly differently so do what suits you and Sophie best.
I've been reading a lot of behaviourist articles recently as a friend of mine is doing a qualification so passes the stuff on and what I've read supports the idea that grazing is a part fo a cat's natural behaviour. Also very useful for cats with boredom issues- the articles I have read on using fouraging as part fo a programmes have been very interesting.
Again, lots of different opinions not only here but among professionals too so try things and then go with whatever suits you and Sophie.
