Hello and a warm welcome
I feed my cats either Hills science diet (chicken) or Orijen which is 75% meat in a biscuit form (available from zooplus) and they do great on it. Ive tried others but ended up with jippy tums. I sometimes add a little Hills pouch to the dry food as a treat.
Mine too ,like some of the others have mentioned also get the odd tin of Tuna (i always buy it in spring water as was told Brine is bad for cats??).
All the best, Ang x
